Bug 187444

Version:            (using KDE 4.2.1)
Compiler:          gcc-c++ 4.3-34.168 The compiler is inatlled from repo: http://download.opensuse.org/distribution/11.1/repo/oss/
OS:                Linux
Installed from:    SuSE RPMs

No matter what I do, it would crash after just a few clicks...
Usually when I right click on a class and than properties and I change stuff there and if I wanna change some data for another class it would crash.
This time it crashed when I closed it.

umbrello -v:
Qt: 4.4.3
KDE: 4.2.1 (KDE 4.2.1) "release 103"
Umbrello UML Modeller: 2.2.1

However I get this message after it crashes: 



Unable to create a valid backtrace.

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, 
or the stack frame was seriously corrupted in the crash.
