Bug 324053

Application: kmail (4.11)
KDE Platform Version: 4.11.00
Qt Version: 4.8.5
Operating System: Linux 3.10.9-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed:

Kmail looked like it was stucked while deleting whole bunch of emails so I've closed it and started again, instead of staring up backtrace window showed. This happened few times before.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
