-- Information about the crash:
The two class that I copied was linked by a composition link.
If I copy/paste the two classes from the class tab to the other one, one by one there is no crash.
If I copy/paste a class wit the link it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Umbrello - Outil de modélisation UML (umbrello), signal: Segmentation fault
