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 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Trying to drag and drop the content of a .rar into the file browser. Browser and ARK crashed then. It happens all the time. Furthermore, it was a NTFS partition to drop the files into. However, often the "explorer" has crashed before already (there are no symbols on the desktop anymore and so on).
