Application: umbrello (2.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Was testing the code generation wizard using a simple test class. Had already generated a Java and PHP class (without closing the wizard), and when I tested C# it crashed.

Can't seem to reproduce it though and the back-trace doesn't tell me much. Perhaps it makes more sense to somebody more familiar with the code.

Note, I am running this on Gnome (Ubuntu 10.04 alpha), if that matters.

The crash does not seem to be reproducible.

 -- Backtrace:
