could be a plastik bug, but the ::shade calls in (apparently) the button code don't look problematik... So I guess it's rather kcolorscheme or even Qt
Actually... the only way I see offhand that this could happen is if color.spec can be dereferenced and is > 4, but color.ct cannot be dereferenced. If this is reproducible, can you try to attach with gdb and see if color looks okay? My guess is it will be bad.
waiting for the gdb output to decide if it is a kcolorscheme or Qt bug.
