Hi there,

I just ran into a problem with umbrello 2.1.0.
The application freezes on startup. I guess this is connected to the config files. If I delete all configs for umbrello I can start it normally.
But when I open an .xpi and exit the program it never comes up again (freeze) and uses 100% cpu.

Here is some output:
jens@magni:~# umbrello -v
Qt: 4.4.0
KDE: 4.1.00 (KDE 4.1.0)
Umbrello UML Modeller: 2.1.0

The mremap continues just the numbers get bigger and the interval between the mremap messages get longer.
