Application: kmail (1.13.6)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.37-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I asked for a system shutdown (from the kde menu), then Plasma and all the other apps disappeared, and Dr.Konqui opened, about this crash of KMail.
- Unusual behavior I noticed:
It is maybe not linked, but KMail took 90% of the CPU sometimes (today for instance) so I kill the process and I run KMail again.
(And at first KMail start of the session, Akonadi seems to be started with it, and it complain about some errors in log files, pressing "Close" makes KMail to exit)

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
