hm, could you try to strace it and/or attach gdb to it and figure out
what's wrong? (perhaps involving the Kaffeine developers too?) As long
as it's not a kernel level crash i cannot see how the scheduler could
directly cause this - other than by accident creating a scheduling
pattern that triggers a user-space bug more often than with other
schedulers.
