[Digikam-devel] Crash when closing digikam immediatly

[Andi Clemens]

To get the crash, you seem to need many albums, and, in the best case, have an 
thumbnail set for every album.

It takes a while until the album folderview is filled and when you close 
digiKam during this process, you can crash it. Everytime.

I will try to add a kdebug().
