Description Petr Bohac 2010-02-12 04:27:33 UTC
Application that crashed: digikam
Version of the application: 1.1.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-174.2.3.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
Digikam crash when I try to change shortcuts scheme.

How to reproduce:
1) Create new shortcut scheme (Digikam crash, but not that reported)
2) Start Digikam again and switch to newly created scheme (this crash)

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
