Application: umbrello (2.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.30.10-105.2.23.fc11.i586 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
System is running in a VirtualBox container on Windows x86 Vista Host, with unmodified  Fedora packages.

Problem:
Umbrello crashes when creating a foreign key constraint in an entity relation diagram. 

How to reproduce (Always):
Create two entities named 'foo' und 'bar'
Create some properties for 'foo' and 'bar', most importantly 'foo'.'id' (int), 'bar'.'id' (int) and 'bar'.'foo_id' (int)
Now - in the properties popup of 'bar' - add a new foreign key, e.i. 'bar_foo_id_fkey',  mapping 'foo'.'id' to 'bar'.'foo_id' and press "OK" or "Apply" -> segfault

Expected behavior: 
A new relation / constraint is added and visible in the outline view, and its possible to add more foreign_key constraints, or edit existing ones. 

I'd like to test if working with foreign constraints works for already created files. So if anyone could provide me with a (dummy) Umbrello project file which has some relationships in it, I'd be more than willing to test if the problem persists.

The crash can be reproduced every time.
