Comment 1 Snark 2009-04-18 12:51:34 UTC

Can you get a better backtrace?

Comment 2 Fernando Miguel 2009-04-18 20:29:45 UTC

> Can you get a better backtrace?

You mean with debug symbols?
if so, the launchpad retracers already have them
https://bugs.edge.launchpad.net/ubuntu/+source/ekiga/+bug/362804/comments/4


plus i just tried to run ekiga with kernel Linux blubug 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux

and it run fine (opened unlike last time), but still generated a .crash file

Comment 3 Snark 2009-04-19 06:54:16 UTC

Well, I had hoped for a more refined backtrace :-/

is it easy to reproduce?

Comment 4 Fernando Miguel 2009-04-19 10:41:48 UTC

i can open it now without crashing.
still when I close it, CLI always says Segmentation fault, but no .crash is being generated

Comment 5 Snark 2009-04-19 11:51:00 UTC

That crash on exit is another issue entirely.

Since the bug doesn't seem to have reappeared, I'll close that report. Feel free to reopen if you get it again.

Comment 6 Pedro Villavicencio 2009-05-14 19:28:56 UTC

the downstream report contains a backtrace:

Snark, is the trace above a valid one?

Best regards,
