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

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.

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.
