Painting on filter masks works, you can test that by replacing the code in
KisFilterMask::apply with the same code from the transparency mask. After
doing that the filter mask works as a transparency mask (suprisingly without
the crash from the transparency mask), so I supect that something goes wrong
when the filter is applied.
