Comment 1 Thomas McGuire 2007-09-06 15:24:08 UTC 
How can the problem be reproduced? I don't get crashes when deleting messages.

This backtrace looks useless, it seems that the crash is deep inside Qt, it should not crash like this. Maybe the crash is caused be invalid compiler optimizations? Please try to recompile Qt and KMail without any optimizations.
Also try to get a better backtrace, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Comment 2 Alex Ivasyuv 2007-09-06 15:29:14 UTC 
I also delete letters normal without any crash, but some times, when I try to delete - Kmail - crash.
Thats all. I not always but some times. If it was be always, I'll be run it thought gdb...
Comment 3 Christophe Marin 2008-06-26 18:22:08 UTC 
Is this bug still present ? If so, could you install the debug packages and provide a backtrace ?
Comment 4 Christophe Marin 2008-11-19 12:50:55 UTC 
No feedback (comment #3) nor useful backtrace (comment #1). Closing.
