This bug is now fixed (workarounded) in the overlay PPA, ie the unity8 doesn't hang anymore on boot:
libusermetrics (1.1.1+15.04.20150427-0ubuntu1) vivid; urgency=medium
[ Pete Woods ] * Stop using shared DBus connections (LP: #1421009)

The bug will stay open for the possibility of getting the reworked QDBus from upstream at some point.
