Hi,
this is known to happen on some systems. Sometimes it helps to run with a
different style for QT (or KDE), the dynamic_cast at the top seems to cause
this with different configurations.

Are you using a different Qt-installation for MusE than the one that
was compiled with your KDE? I've heard that might be the cause of
the problems with the styles.

most certainly a build-system issue, no other reports for
quite a while, closing.
