That seemed likely, but I couldn't tell why it would result in this
behavior or how to fix it. Here's the relevant Debian patch. (Note that
I'm doing this in Debian because the luxi.c font is non-free; this will
probably be an issue for the FSF as well.)
I suppose I could be using the API wrong, but it seemed rather
straightforward and very similar to the regular gnubg code.
