-- Information about the crash:
After my Umbrello crashed (again... probably 10th time today), a class called LOST (with some suffix) has been added to my module. When trying to remove it, Umbrello crashes (again !)

The crash can be reproduced every time.

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