Are you on a PCI machine with a mach64/ATI (sun calls is "PGX")
graphics card in it?  If so, I've seen this before.  The same will
happen if you load up a jpg file in gimp at 16 bpp, usually the X
server calls abort.

I sent Jakub this patch a few weeks ago. I discovered the problem
while porting Debian to the UltraSparc.  It fixes the problem.  (It's
very easy to track these things down with gdb if you have a Debug
build of X lying around.)

Yep, I have this in my XFree86 patch queue, but have not managed to make new
rpms yet (I'd like to do some hacks in it still). Sorry.

Cheers,
