Application: step (0.1.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)

Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: Trying to delete a "Gas Object" which was resized couple of times. some "Gas particals" were out of the red box (the box which shows the boundary of the particals). I think the particals should not have been out of the boundary box, in the first place.

-- Backtrace:
