Bug 240944

Application: krusader (2.2.0-beta1 "DeKade")
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.33.5-112.fc13.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Fedora13: When installed update 2.2 (over 2.0) the file list icon size was somehow reset from my previous settings of 16 to 22. When I started the Krusader, opened config dialog -> Panel -> view, set the filelist icon size to 16, pressed apply and close and got coredump

The crash can be reproduced every time.

 -- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
