That's quite mysterious. Oh! I bet that someone's trying to destroy a
constant font; the check for constantness is two lines down. So I bet
it would work if I moved this two lines down. But also, there's a
memory leak here. I've committed an improved version, which, I believe,
gets rid of the memory leak as well.
