Looks like a null dereference.
Odd. ok. I will take a look into it... i386? I see your gdb is el5... but this is on f8, right? Is there anything in your ~/.twinkle/twinkle.log that pertains to this?
Yes, it's i386. The gdb output is from el5, but the same behavior applies for f8 too. No, nothing in twinkle.log.
Looks like this might be something in the ccrtp libs. What version of ccrtp do you have installed? can you install the ccrtp debuginfo and re-run gdb? Can you generate a twinkle.log with a failed session and attach it anyhow? (Upstream asks for that on all bug reports).
I take it you are only seeing this in devel, not F8? Can you try the twinkle from this scratch build (as soon as it's done)? http://koji.fedoraproject.org/koji/taskinfo?taskID=251349
Houps, sorry for late answer. I need to reorganize my bugzilla mails I think. My ccrtp version is ccrtp-1.5.1-1. As the scratch build does not preserve the source rpm I can't try it. I'm using this twinkle package under RHEL, recompiled from Fedora.

Comparing straces and an educated guess shows that switching from ALSA to OSS seems to fix the hang on clicking BYE. This might be heavily related to this problem.
True, this solves the problem. I just found another user having same problem.
Marek, (In reply to comment #11) > True, this solves the problem. I just found another user having same problem. I'm not seeing this problem myself. What Headset are you using when calling with twinkle? Is there any correlation? I'm on a Logitech headset with USB adapter. regards, andreas
Andreas, no headset, using my build-in sound card in T60.
Marek, what about the others? Internal card as well?
Yes, however after I've reinstalled my computer I don't see this error. Andreas can you please work with Igor Donev to get this resolved?
You no longer see the issue? Do we have someone who can duplicate it? I still don't see it here at all...
Any further news here? Or should we just close this out?
(In reply to comment #17) > Any further news here? Or should we just close this out? Kevin, closing. Thank you for your time, this bug report itself has not been very informative from my side. If I see the issue again I'll make sure to troubleshoot it and get proper backtrace as well.
