Application: umbrello (2.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-server x86_64
Distribution: Ubuntu 11.10

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

I used a Ctrl-Z keypress to attempt an undo of a cut of an Actor from a diagram with a few Actors, Associations and Use-Cases. The cut Actor was associated to 2 us-cases before it was cut.

The crash can be reproduced every time.

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