Bug 260827

Application: kontact (4.4.8)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I right clicked on the left hand icon bar (the bar that has icons for KMail, Address Book, Notebook, etc.) I changed the setting from text under icons to no text, and Kontact crashed.  I tried a couple times, and it crashed each time.  My changes were not saved.  Then out of curiousity, I changed the size of the icons, and that crashed contact too.

The crash can be reproduced every time.

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