Application: ark (2.14)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I started to compress a folder to a tar.gz. archive using Dolphin's context menu option. Before the task was completed I tried to stop the process. Then, Ark crashed.

I'm not sure but I think Ark showed an empty dialog just before crashing.

 -- Backtrace:
Application: Ark (ark), signal: Segmentation fault
