I do not guarantee the other versions exactly match the backtrace but it is mostly similiar (with some updates) to the versions listed in Bug 558495.
Comment 1 Matthias Schneider 2008-10-30 19:48:04 UTC 
Can you provide a complete backtrace with 

thread apply all bt

?
Comment 2 Jan Kratochvil 2008-10-31 11:20:53 UTC 
As I run the default -O2 rpm build the variables dump is not much useful.  Sure I could rebuild all the libraries with `-O0 -g' etc. but I just tried if the bug is not more obvious.

The new backtrace is still unuseful, since it only shows one thread. Like I said a 
thread apply all bt is needed
even if it does not show all debug symbols

Sorry, I did read it wrong (it did not show me it has threads before due to some other local problems).

I suppose this is the same as the Write crash (recently fixed), since it is in the same code (publish) and only after some hours of being idle.

Jan, please check with current svn/git or try the new 3.2.5 ekiga (which will appear very soon).

Running now ekiga-3.2.5-2.fc11 opal-3.6.4-2.fc11 ptlib-2.6.4-2.fc11 (x86_64)
and after a day of idle it cannot call even <sip:500@ekiga.net>.  It no longer crashes but the call hangs up immediately without getting connected.
Simple restart of Ekiga makes <sip:500@ekiga.net> working.
Running now with `-d 4' and going to post some results when it gets idle enough.

This is bug #579938, so we can close this bug about the lockup, is that right?

Bug #579938 is talking about broken reception of calls while calls originating works there.
Anyway it can be considered a different bug I am going to post/follow-up so closing this one, thanks.
