Bug 258263

Application: umbrello (2.5.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-61.fc13.i686.PAE i686
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
- What I was doing when the application crashed:
I hava a database diagram with 15 entities (tables) and the relations between them (described by foreign keys). Some of the relationship lines intersect and are hard to follow/interpret so I wanted to move one of the entities. I can move it around but as soon as I touch the tables in its proximity the program crashes.

The crash can be reproduced every time.

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