Bug#747874: gnome-music does not start

[Julian Andres Klode]

Package: gnome-music
Version: 3.12.1-2
Severity: grave

I just installed gnome-music, but it does not start at all, it just 
hangs waiting for a mutex. I get the following warnings on the console:

/usr/lib/python3/dist-packages/gi/module.py:178: Warning: cannot register existing type 'TrackerSparqlConnection'
  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:178: Warning: g_once_init_leave: assertion 'result != 0' failed
  g_type = info.get_g_type()
/usr/lib/python3/dist-packages/gi/module.py:212: Warning: g_type_get_qdata: assertion 'node != NULL' failed
  type_ = g_type.pytype
/usr/lib/python3/dist-packages/gi/module.py:226: Warning: g_type_get_qdata: assertion 'node != NULL' failed
  g_type.pytype = wrapper
/usr/lib/python3/dist-packages/gi/module.py:226: Warning: g_type_set_qdata: assertion 'node != NULL' failed
  g_type.pytype = wrapper

It seems to fail in /usr/lib/python3/dist-packages/gnomemusic/widgets.py, line 48:
    tracker = Tracker.SparqlConnection.get(None)
the top of the gdb backtrace is:
