[KHTML developers listen under kfm-devel at btw]

The actual problem is more KHTML related: often it repaints too much, and 
animated gifs trigger a repaint of the complete viewport and not just the 
tiny rectangle of the gif. 

I do wonder though if the libungif version would have less bugs than the Qt 
GIF reader (which is still terrible buggy).
