I already had jackdbus disabled in my search for a solution, was one of the steps I took. And I filed a bug report, describing behavior with pulseaudio-module-jack, and without it, in case I'm not alone with this issue. In Ubuntu 14.10 this wasn't an issue either for me and I kept it in place too. Luckily, using two sound cards, internal for regular audio, and audiofire12 for real audio work goes just fine :-).
