The image is 17449x14534. Mozilla needs 17449*14534*3 (726MB) in it's own 
process to open it. Mozilla then tries to copy the entire thing to the X 
server process which may need as much as 17449*14534*4 (967MB). Your virtual 
memory (RAM + swap) may need to be >1692MB. That's a lot. If you don't have it 
the kernel will kill mozilla which is probably what's happening.

This is a known problem. See bug 233262 among others for some more info.

Sorry for the spam but if you don't have the 726MB then mozilla may be 
crashing because of bug 166862.
