Bug 246742

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32.16-150.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I installed some widget in dashboard: notes, unit converter, calculator, yawp and world clock. This error seems related to world clock. After that, plasma-desktop crashes after every boot. If I launch plasma-desktop in already started (and crashed) session, plasma crashes immediately.



The crash can be reproduced every time.

Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
