Oh okay i understand. Well this is solved then. Sorry for the un-needed report !

it behaves the same way but as you can see there is no eyedropper like on a "normal" color menu when filling tiles.

It crashed with the default blender scene i can't even paint on the texture just by semecting any newly created blank tiled texture and selecting it in the tool properties in single image makes blender crash. Here is a video of the bug happenning

Sorry if it was vague but it's basically the thing i've done .I tryed it several times and every time after a few seconds of painting blender crashed. Just by painting on tiled textures. If doing this didn't caused a crash for you maybe my system is part of the problem.
