Hm... That's a difficult question. The  best tool seems to be helgrind
(valgrind --tool=helgrind krita), but I don't actually know how to use
that myself... When running krita with helgrind I do see a lot of errors.
It might be easier to attach a breakpoint at the destructor of QApplication,
run under gdb and check for running threads there.
