Application: umbrello (2.10.4)
KDE Platform Version: 4.10.4 (Compiled from sources)

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

Umbrello crashed when I used many times "undo" and "redo". Just make "undo" at 20-40 operations, then ~10 "redo", then again "undo"... and again.

-- Backtrace:
Application: Umbrello (umbrello), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
