oops, core is 19Mb, so not attached. ask any info if you need.

[Comment 3 Lars Wendler (Polynomial-C) (RETIRED) 2009-03-23 20:54:25 UTC]

Could you please provide a backtrace of the crash?

core itself is here: http://rapidshare.de/files/46299891/core.bz2.html

as i understand, to produce full debug build, i have to rebuild all world/libraries with debugging - i want to avoid this.

[Comment 5 Olivier Crete (RETIRED) 2009-03-24 23:20:09 UTC]

Yes, this crash is not so useful, but I'm having problems with pidgin too, so I'll look into it.. But my guess its some kind of upstream suckiness

[Comment 6 Peter Volkov (RETIRED) 2009-12-17 17:24:27 UTC]

Without backtrace or debugging information it's hard to do anything here. Vladimir, to get good backtrace you need to rebuild glib, gtk+ and probably glibc with debugging symbols. Core file without debugging symbols also hard to analyze. Please, try to get backtrace with function names, as described in:

http://www.gentoo.org/proj/en/qa/backtraces.xml

Well, it didn't work for quite a long time, but after recent
updates looks like it started to work again.
Now i have pidgin 2.6.3 and see no problems.

Who knows what were the problems? No one knows... There are
thousands of possible reasons and i was not going to turn
my working machine into debugging battlefield. Nice it's working
now.
