On a fresh Leap 15.1 install with XFCE4 desktop I can't start up the XFCE
bluetooth settings.
When manually starting blueberry from terminal I see this:
Traceback (most recent call last):
  File "/usr/lib/blueberry/blueberry.py", line 5, in <module>
    import rfkillMagic
  File "/usr/lib/blueberry/rfkillMagic.py", line 7, in <module>
    from gi.repository import GLib
ImportError: No module named gi.repository

So I assume there are missing RPM dependencies?
After manual installation of python2-gobject. I no longer receive this error,
but the settings window still does not open.
Now I see this appearing in journalctl when starting blueberry:
segfault at 0 ip 00007fce0b50f999 sp 00007fff8712edc0 error 4 in
libgtk-3.so.0.2200.30[7fce0b21a000+707000]

So on a fresh Leap 15.1 install with Xfce desktop, bluetooth is not functional.
