after updating to rygel .22, tracker backend does not work

[Mehmet Giritli <mgiritli giritli eu>]

tracker version is 1.0.2 and I see these after the upgrade:

mordor rygel[10766]: (rygel:10766): Rygel-Tracker-CRITICAL **: file
rygel-tracker-plugin-factory.c: line 220: uncaught error: Error spawning

--binary-syntax --close-stderr': Child process exited with code 1
(g-spawn-exit-error-quark, 1)


I also see these but don't know if they are related:

Both error messages started appearing after upgrading to 0.22.2. Rygel
server does not appear unless I enable media export plugin.

I'm not sure if it is a bug or more likely, a configuration error.

Regards.
