-- Information about the crash:
- What I was doing when the application crashed:
Started compressing a file from dolphin (I don't remember if it was bzip or zip), and hit 'cancel' during the process. 
The result was a popup declaring that so-and-so had crashed.

The crash can be reproduced sometimes.

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