Bug 210378

Application that crashed: digikam
Version of the application: 1.0.0-beta5
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-13-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
Digikam crashes repeatedly when closing the application. I had loaded 2 photographs into the lighttable and done a "edit" on one of them.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
The current source language is "auto; currently c".
