qole: thanks, this is assume!

I am trying to play an audio/x-wav file using mplayer.
after the last update I now see Open with dbus switchboard.
However , when I click this I get the error:
No Handler configured for this type

In Handlers I see a line : Mplayer /usr/bin/mplayer -quiet "%realparams%"
in URIs I see the line: audio-x-wav hildon-dbis-switchboard-desktop
In Defaults I see audio/x-wav hildon-dbis-switchboard-desktop

so what am I missing?
