Sharpening twice

Running the sharpen filter twice makes Krita crash -- curiously enough in the
display code, as if the filter leaves the paint device somehow in a wrong
state. More worrying is that running the sharpen filter with valgrind
--tool=memcheck gives. Lots of invalid reads... And running the filter
changes the extent of the layer a lot. I've tried in vain to fix this today
-- maybe anyone else has an idea?
