Bug 285753

Application: kontact (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1-desktop x86_64
Distribution: "openSUSE 12.1 RC 1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I've never get a crash if I turn on the lappy, and turn off it afterward.
Now today, I've start it, then have to go, put it on suspend to ram mode, after telling kmail to work offline. I've wake up, work during 2 hours with utms connection, and sleep it again.
Back to office, I wake up, work online. Then ask for shutdown. the crash appear at that time.

The crash can be reproduced every time.

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