Application: umbrello (2.6.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686

-- Information about the crash:
- What I was doing when the application crashed:
Crash occurred while building a class diagram. Presses Undo/Redo several times. Then  drew "Implements" line from one interface to another. Crash took place when the mouse button has been released so a new connection had to be drawn.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault
