Doru

To me this is not really a good bug report. 
	How can we reproduce it?
	What is a big image?
		
The first thing to do is to get a simple reproducible case.
This is what pavel did with the crash on normal images. 
Can you see if you can do something like that?
It will help us trying to fix it.
