A patch would be great! I haven't really thought about exactly how the
implementation needs to be done, but I fear it might get quite involved.

It would be really good to get a test case for this case too, so we better
write that up so that we can verify the fix easier. Perhaps we could base it
on test 552 which at least is somewhat in the same ballpark.
