Actually, in my case it was apparmor-notify. It was starting via the old /etc/X11/Xsession.d mechanism which made it start on a different bus. Moving the autostart to /etc/xdg/autostart fixes this issue for me. Thanks to Sebastien and Marc for helping me diagnose this. Assigning to myself-- I'll fix it in the next apparmor upload. If people are still seeing this issue and they do not have apparmor-notify installed, please file a new bug.
