Ok. I had hoped to reproduce the problem with pristine sources, in
order to verify that I was able to show it not appearing with my patch.
However I have been unable to create a situation in which the problem
appears. So I attach the patch that I came up with. Please test it.
I added a loop counter, to verify that we don't loop indefinitely. I'm
not sure that it's the best way to do it, but I'm too coward to leave it
without any check.
