Application: rocs (1.5)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-fs i686
Distribution (Platform): Debian unstable

-- Information about the crash:
- What I was doing when the application crashed:

I dragged some nodes into the area (around 10), used the Make Complete tool and then Deleted one of the nodes with the Delete tool button. Rocs crashed immediately.

The crash can be reproduced every time.

-- Backtrace:
Application: Rocs (rocs), signal: Segmentation fault
