epiphany-gecko crashed with SIGSEGV in __kernel_vsyscall()

Bug #230808 reported by Trouilliez vincent on 2008-05-15
Affects Status Importance Assigned to Milestone
Fix Released
xulrunner-1.9 (Ubuntu)

Bug Description

Binary package hint: epiphany-browser

Since upgrading to Hardy, Epiphany keeps crashing, say about once a day.

It generally seems random, with no obvious cause, but managed to find a way to reproduce the particular crash that his apport bug report refers to. Hopefully fixing this particular crash will also fix all the others that I can't find a pattern to.

To reproduce this bug:

1) visit this web page:


2) Increase the fon size using the keyboard shortcut: Control + "+".

This causes Epiphany to crash either instantly, or following a minute or two of hanging.

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

Changed in epiphany-browser:
assignee: nobody → desktop-bugs
importance: Undecided → Medium
status: New → Incomplete

Backtrace attached.

However, despite I installed the debug symbols/packages for epipnany-gecko as well as epiphany -gecko-extensions, well despite that, when I asked gdb for the backtrace, as you can see from the log, it complained that there was NO degug symbols ?! How comes ? :-/

(gdb) backtrace full
#0 0x00000000 in ?? ()
No symbol table info available.

the crash seems to be a xulrunner one, you should install xulrunner-1.9-dbgsym too

Done. I have attached the resulting backtrace.

Good catch

 affects ubuntu/xulrunner-1.9
 status triaged

 affects xulrunner
 status incomplete

Should be forwarded upstream

i cannot reproduce this anymore with latest package on jaunty could you please test as well Trouilliez and report back? thanks in advance.

Hi Perdro,

I can't tell about Jaunty as it's not released yet so I can't test. However I am on 8.10 now, and epiphany doesn't crash anymore on this web page. So I think we can close this bug ! :-)
