Otter crashes and burns in Ubuntu Linux

2017-08-14, 03:28:35

I installed Otter Browser in Ubuntu 14.04. At first, it seemed to work fine, but then it started freezing and hanging, and then it lead to a segmentation fault and coredump.

Please help! Right now it seems my only choice is to purge Otter browser. I had to use another browser to even post this thread! Maybe the problem is the package I used, and some other form of installation would work.

Here is some information about the last crash:

otter-browser crashed with SISEGV in QWebHItTestResultPrivate::QWebHitTestResultPrivate()

Segfault happened at: 0x7fdb06521d42: mov (%rdi) %rax
reason: reading NULL VMA

source package: otter-browser
Installed: 0.9.09.01-1~trusty~ppa1

Follow-up: I tried the AppImage, but it didn't work at all. I was able to download and execute the sample program, Subsurface. But I followed the same steps for the otter-browser AppImage, and double-clicking it just did nothing.

@gracious1, try running AppImage from terminal and copy output, note that you usually need to mark it as executable first.
BTW, that version of Ubuntu is kind of outdated...

"Kind of outdated"

? Ubuntu 14.04 is officially supported until 2019.

And of course I marked the AppImage as executable before I tried to run it. As I stated in my post I followed all the steps for the otter AppImage as for the sample AppImage download. But even if I hadn't done the sample first, I would have known to chmod to executable. I have been using UNIX and UNIX-like operating systems since my undergraduate days.

I re-installed from the PPA, and ran from the Terminal. The only output I get is:

Code: [Select]

$ otter-browser
Segmentation fault (core dumped)

(BTW, where are the preference/profile files for otter located? Haven't successfully purged those.)

@gracious1, Windows XP was still supported until recently. ;-)
So you are getting crash after using both that outdated package (14.04 uses very outdated Qt version...) and fresh AppImage?
Please check if you are still getting crash with AppImage after renaming configuration file.

BTW, which OpenSSL versions do you have installed?
AppImage uses official Qt bianries which expect 1.0.x as libssl.so (or with some suffix), OpenSSL 1.1 is not backwards compatible.
It also requires GStreamer 1.0.

About backtrace, AFAIR that Ubuntu version uses the most bogus QtWebKit package imaginable, using some snapshot from Qt 5.1 together with Qt 5.2 (due to issues with their failed phone attempt, AFAIR it was mentioned in changelog of that package or elsewhere).
Anyway, any QtWebKit version older than 5.4.x is pretty unstable and all versions older than 5.212 are outdated.

You should focus on AppImage.
You can try to extract it and try gdb again (run otter-browser.sh first).

Hello. Sorry for the delay in getting back to you.

I have today re-installed otter-browser from the repository (using apt-get). So far, it seems to be going well, despite the apparent antiquity of my system

, but I notice a few oddities.

For example, in the Preferences, the settings relating to passwords are grayed out, like so:
https://s6.postimg.org/4gburjlbl/Passwords-grayed-out-_Otter_01.png

Likewise, remembering search and form history are grayed out.

I also notice something else. The otter inside the O is appearing everywhere in my system, not just in Otter application windows. Here, for example, is SeaMonkey:
https://s6.postimg.org/521a70xbl/otter_issue_2.png

All my windows in every application look like this, with the otter-in-the-O in the upper left-had corner!

@gracious1, it's an old version and Passwords Manager wasn't available yet.

That is normal even for current master.

That might be displaced tray icon, try disabling Browser/EnableTrayIcon in about:config.

You can try newest AppImage too (weekly 191), there were some changes that might allow it to run for you.

What is an old version? The version of Otter that I am using?

Code: [Select]
$ apt-cache policy otter-browser
otter-browser:
  Installed: 0.9.09.01-1~trusty~ppa1
  Candidate: 0.9.09.01-1~trusty~ppa1
  Version table:
*** 0.9.09.01-1~trusty~ppa1 0
        500 http://ppa.launchpad.net/otter-browser/release/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status
So the candidate in the PPA is not up-to-date?

Nope. Doesn't work.

Arrrgggh! Otter crashed again while I was editing my last post.

It crashed with signal 11. Here is what I got in the crash report:

Quote

This problem report is damaged and cannot be processed.

OSError('invaldi core dump: BFD: Warning /tmp/apport_core_c5uyjk28 is truncated; expected core file size >=188798320, found: 924090586.',)

Not very helpful, I know.

And the AppImage just will not run.

The sample program (Subsurface-4.6.2-x86_64) still runs just fine, so I am inclined to think there is something wrong with the AppImage not with my system.

It looks as though I am missing certain dependencies. Would it be possible to update the deb packages in the repository to include the libraries that not every LTS disto has access to? I seem to have better luck installing that way.

I really want to make this browser work, and I would appreciate any help. Thanks.

For me the latest weekly AppImage (191) won't start either due to some libssl nonsense (see here). OpenSSL is pretty frustrating.

(I guess you could always build Otter yourself.

I think that this would be the best option for such old version of Ubuntu, it uses Qt 5.2 so even that alternative approach for AppImage wouldn't help, it's too old Qt version.
