DBus issue

[Matthijs Tijink]

Hi Nico,

In case you're still stuck: you can always just send the dbus 
"PropertiesChanged" signal yourself, instead of letting Qt handle it. It's 
what I've done in my own MPRIS project. Probably not the easiest way though.
I don't know the specifics about what you're doing, but maybe this helps.

Kind regards,

Matthijs Tijink
