    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.
