Rygel plugins wont load with error

[Hugo <hugo calleja gmail com>]

Im trying to configure Rygel for the first time and can not get it to work. I get this error when it tries to load any plugin:

(rygel:30575): Rygel-Tracker-CRITICAL **: file rygel-tracker-plugin-factory.c: line 215: uncaught error: S'ha produït un error en engendrar la línia d'ordres «dbus-launch --autolaunch=861b9cf4450747186e93f0fc50b3cbb4 --binary-syntax --close-stderr»: El procés fill ha sortit amb el codi 1 (g-spawn-exit-error-quark, 1)

As I said, its not only with tracker but with any plugin Ive tried.

Im running Ubuntu 12.10, with rygel from the stable ppa (version 0.16.3-1ubuntu1-ppa1~quantal1). I have tried it with the unstable ppa and with the last tarball 0.17.5.1) and could not get it to work either. I also tried the git repository directly but could not even compile, make gave a compilation error.

This part is probably not important but just in case: the machine has 2 network interfaces, one managed by the network manager and the other configured directly at /etc/network/interfaces (it has to be this way). I want Rygel to use the second one (the one on /etc/network/interfaces) and I have set it up that way. To me it seems its working because of the log, but since I know its given problems before I though i would include it:
