SVN commit 1148489 by pedrol:

A bug in glib-2.22 (https://bugzilla.gnome.org/show_bug.cgi?id=599079) produces a \
crash in FluidSynth 1.1.x when launched from inside KMid, if the user has permissions \
to set realtime priority, used by Drumstick. This is a workaround, resetting the \
scheduler to the default time sharing of Linux.
