On a clean install in a Debian testing chroot, using terminal-based
emacs, everything seems to be working properly.

Whether it was going to the latest auctex (11.86) or the absence of
other legacy stuff (old packages), I can't say.  I can say that starting
emacs in a terminal (-nw) without reading my init file (-q) did not
solve the problem on my main system.
