hi.. I've just discovered this bug when I upgraded to KDE 3 (and spent ages
installing every single KDE package, thinking I was missing the icons :-( )

Switching to 24 bit truecolor (instead of my default 32 bit truecolor) has 
fixed
the problem. Using XVision on the 32 bit display meant that the pictures 
displayed
OK (there are other bugs in XVision though!). I suspect that the fact that 
XVision
doesn't offer 32 bit pixmaps is what makes the difference.
