Bug 230130

Application that crashed: umbrello
Version of the application: 2.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
OS: Ubuntu 9.10 with gnome
GNOME: 2.28.1 (Ubuntu)
Umrello: 2.3.2
KDE: 4.3.2

I've just install Ubuntu a few days before, i was looking for an UML editor and i found Umbrello. I was just trying it doing a state diagram. I put de initial state, a state and i linked them with the transition arrow. I move arround the state and then (trying made the arrow look better) the arrow show a vertex, so i go undoing for it to desapier, but it didn't. After undoing betwen 10 ~ 20 times y redo some ones and it simply crash with a segmentation fault.

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