Fix looks correct to me. If someone without 400K of outstanding patch
could commit I'd appreciate it.

If you're using dbus multithreaded, you may want to run "valgrind --
tool=helgrind" on it and investigate some of those issues; last I
checked it had several complaints. test/glib/test-profile is a simple
multithreaded test app if you need one. This may find some bugs that
would bite you later.
