Bug 250877

Application: systemsettings (1.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-20-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
I plugged in my Nikon D5000, opened up System Settings and selected the Camera entry.  Once in there I clicked on the icon for my camera and then clicked Configure.  I performed this action twice and it crashed both times.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
