Bug 259015

Application: kontact (4.6 pre)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.1
Operating System: Linux 2.6.31.14-0.4-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
kontact loaded with akregator and when I clicked on the left pane to activate kmail, it (kontact) crashed. I tried it twice and it did that each time

The crash can be reproduced every time.

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