Description Andrey Brozhko 2006-09-08 08:47:59 UTC
Version:           unknown (using KDE 3.5.3-4.1, Fedora Core release 5 (Bordeaux))
Compiler:          Target: x86_64-redhat-linux
OS:                Linux (x86_64) release 2.6.17-1.2157_FC5

I left kontact (in kmail) running overnight and when came in the morning there was this crash report. I am sorry I don't know how to reproduce it. It's been left running overnight before with no crashes (however after a while mail will stop being be collected from my POP server - see kmail bug 131013). Here is the crash backtrace:
