I have a similar backtrace here. I was setting my status to online, when a window with an incoming message showed up for a moment and then Kopete crashed.

The backtrace:

This crash report is at least 3 years old and there were no further comments or status updates since then.

Therefore we believe that this crash is already fixed in recent KDE 4 versions or the backtrace is no longer applicable to the current KDE 4 sources.

If the crash still happens with a recent KDE version (4.10.5 or 4.11), please add an updated backtrace or provide steps to reproduce. For more information, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

(To prevent automatic closing of this bug in the future, please set the bug status to ASSIGNED or CONFIRMED)

I think I have this problem, Kopete is crashing for me once I try to establish a OTR session and then I send a message to my friend, Kopete will crash just right there.

How can I get a back trace? Please re-open this bug, or should I start a new one?

My system info:

Arch Linux x86_64
Qt: 4.8.5
KDE Development Platform: 4.12.0
Kopete: 1.6.0

Thanks.

I also wanted to say that I can reproduce this crash at will, the crash happens when I send a message, once the OTR was established or when it's in the process of being established.

Let me know if you want a backtrace.

Diego, 4.12 regression when _sending_ a message is bug 328999.

Christoph,

Thanks, I will report my problem in bug 328999 instead. I wasn't aware there was a thread for that issue already.
