press ctrl-a or choose selection/select all. Select the fill tool. Check "fill entire selection". Click. Nothing is getting filled!

I'm fairly sure that this is caused by the exact bounds of a layer coincide with the exact bounds of the selection: probably isPorbablyTotallyUnselected is wrong here. Since that's Cyrille's baby, assign to him.

hein ? is it my baby ?

The probabilistic determination of whether a layer is totally selected or unselected is, isn't it?

No, it's bart!
