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 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Ark crashed while not fully loading big archive and after closing it.
This may be because of my system not running smooth because of several torrents threads (Ktorrent) running simultaniously 

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