Thank you taking the time to report this bug and helping to make Ubuntu better. However, processing the crash report to get detailed information for the developers failed as the retracer did not generate a useful symbolic stack trace.
Please try to obtain a backtrace manually following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Hi I was using https://wiki.ubuntu.com/X/Backtracing --> section Backtrace with gdb to generate gdb-evolution.txt file. Please let me know if it is what you need.

Thank you!

I just updated to evolution 2.30.2-1ubuntu2 with evolution-mapi 0.28.3-0ubuntu1 and the problem still exists.

[Randy Barlow (rbarlow)]

Problem still happens with evolution 2.30.3-1ubuntu1 and evolution-mapi 0.28.3-0ubuntu1.

[Pedro Villavicencio (pedro)]

Could you execute 'backtrace' in gdb and also 'thread apply all bt full' after getting the crash and attach the resulting output to the report? you were doing the right thing to get the backtrace but looks like you didn't executed the command which shows the backtrace. Thanks again.

[Randy Barlow (rbarlow)]

This is the requested backtrace info, thanks!

[Pedro Villavicencio (pedro)]

Hello Randy, I've checked the upstream bts and talked with some bugsquad members and the crash seems unique, but we'd like to get some full debugging on it, could you install the libglib2, libgtk2 and just in case evolution-data-server and evolution dbgsym packages and get a new one performing the exact same steps you did before? that'd help us a lot , thanks again!.

[Randy Barlow (rbarlow)]

Here is the gdb session with all the requested debugging symbols installed.

[Randy Barlow (rbarlow)]

I went ahead an ran valgrind on evolution as well since it is a segmentation fault.

[Petko Kolenichev (pkolenichev)]

Hi Pedro,

 I sill experience the same problem. Please find attached requested gdb

Hi Pedro,

I still experience the same problem. Please find attached requested gdb after installing the requested packages.

thank you,
Petko

[Pedro Villavicencio (pedro)]

that was fast!, thank you folks, i'll send this upstream.

[Pedro Villavicencio (pedro)]

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at:
 https://bugzilla.gnome.org/show_bug.cgi?id=629193

[Pedro Villavicencio (pedro)]

Hello folks, the upstream developers are asking for another trace with pango debug symbols, could you install libpango1.0-0-dbgsym and get a new backtrace? thanks a lot.

[Randy Barlow (rbarlow)]

I've installed the debug symbols for Pango, and here is the backtrace.

[Randy Barlow (rbarlow)]

BTW, I did already put this on the upstream bug report for you. I thought the traceback was strange though, as it did not contain the string "pango" anymore, so it may not be that useful.

[Petko Kolenichev (pkolenichev)]

Hi Pedro,
please find attached backtrace after installing libpango1.0-0-dbgsym.
Best Regards!

[Randy Barlow (rbarlow)]

The latest versions of evolution (2.30.3-1ubuntu6) and evolution-mapi
(0.30.3-1ubuntu1) in Ubuntu Maverick allow me to read my mail without this
crash.

[Pedro Villavicencio (pedro)]

still an issue on 2.32 ?

[Pedro Villavicencio (pedro)]

closing the bug then, thanks much.
