Qt Ubuntu Media builds and seems to run with the MP now attached to this bug report.
The Unity 8 starts if I comment out the two offending lines from Notifications/Notification.qml + Components/ScreenGrabber.qml
For some reason I was not able to figure out how they should be changed immediately to set the role without getting some QML error. I changed the backported qtmultimedia patch a bit to state 5.5 - https://launchpadlibrarian.net/220262357/qtmultimedia-opensource-src_5.5.0-3ubuntu1~wily1~test4_5.5.0-3ubuntu1~wily1~test5.diff.gz - and I changed the Unity 8's qml files to import QtMultimedia 5.5 instead of 5.0.
