I'll see if I can get more information by running emacs under gdb. I'd appreciate any suggestions you might have as to where I should look. I forgot to say in my first post that the emacs I'm testing is a pretest of the upcoming emacs-24.1. If I'm not able to figure out what's going on, maybe I'll make an experimental version available so that you can try to reproduce the problem.
