Makes no difference if I have prelink installed or not.

Expected results:
Gimp starts, the world turns and my boss gets off my back!

Additional info:
Video card makes no difference (also happens on the laptop which uses an intel chipset and my desktop box using an nVidia card), doesn't seem to be an selinux fault either.
