If it does not work with gb.gtk, then it is a bug. But if you don't give 
me a little test project that reproduces it, I won't be able to fix it. 
I need it because I have to see what you are doing *exactly* (the bug 
may not be a direct consequence of using PaintImage).

If you have other differences between gb.qt4 and gb.gtk, please report 
them! They are bugs too, except for very specific things that cannot be 
made the same between the two components.

Thanks in advance.
