Bug 313365

Application: kontact (4.9.5)
KDE Platform Version: 4.9.5
Qt Version: 4.8.2
Operating System: Linux 3.2.0-35-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
see headline, I was deleting about 200 messages from a folder in a KMAILdir resource. 

Slowly deleting them one by one seems to work, but CTRL+A, <DEL> /Selecting "Delete Messages" from context menu leads to kmail stalling for hours. A small progress meter appears in the right lower vcorner ("Moving messages") but it never finishes. The only way to solve this is to kill kontact.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
