Where is the code that catches this? I have been trying to investigate a 
Windows specific bug listed in FOR-RELEASE the last couple of days, 
where the same seems to be happening with the splash screen image, 
except Emacs never catches it and it keeps looping. I can see that on X, 
Emacs catches it as you explain there.
