Bug 199813

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
The plasma-desktop app has crashed just after I've closed a digikam window.
it was the 'reconstruct thumbnails' dialog and the main digikam window was minized.

 -- Backtrace:
