What happens is that Save As... reloads the buffer (for a reason that is 
not very clear at this point), which means that all cursors hold bad 
pointers. It seems that, before the biginset branch removed a few full 
metrics updates, we could get away with it (presumably some code 
somewhere fixes the cursors). Now, we have to fix it at the right place.

I propose the following patch. Can you check that it works?
