In the thread "Emacs loops on large images" from the start of december I 
reported that Emacs often loops when trying to display images larger 
than the window. Maybe the problem you have seen is the same.

With gdb I found out that Emacs loops in the while loop in xdisp.c: 
back_to_previous_visible_line_start. It seems that the code searches for 
a completely visible line, but there is no such line because the image 
is larger than the window. I haven't had time to look further into the 
problem and I know nothing about xdisp.c.

I am cc'ing Kim hoping for help.
