@Nicolas: If you are short on time, can we just install this patch?
I've tested it for a while and it works well, and I'm quite sure it is
harmless (doesn't change any semantics apart from fixing the crashes).

@Nicolas: Do you want us to care about this or do you want to have a
look yourself?  I don't want to hurry, I just don't want this to be
forgotten.  If you say you have time in four months, it's still ok.
