Application that crashed: ark
Version of the application: 2.13
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-22-generic-pae i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Ark crashed when I drag and dropped a file-from-a-subfolder-of-the-7-zip-file from Ark to Explorer. Did not have time to drop the file (which was a picture) before it crashed.
Ark is the only KDE soft that I use.
