MuseScore

Hi,
I a new user of mmusescore.

I use Debian, but the Debian package for musescore is too old (1.0), so I downloaded the sources for the 1.1 version, and tried to build them. But this failed because of the can't-compile-with-gcc-4.6 bug, which is already fixed in the SVN, but have not yet been released.

Therefore, I checked out the latest version from SVN, and built that instead.

Now it builds, installs and runs, and I can enter notes, too, but when I click on the "Preferences..." option in the Edit menu, the application crashes (Segmentation fault.)
What could be wrong?
Thank you for your help:

Kristof

ps. If this the wrong place to report problems, then I am sorry.
If there is a how-to about reporting bugs (what extra information is required, etc, etc,), then please show it to me, and I will obey.
