Hi geekos!

I tried "Music" (aka gnome-music) again; Unfortunately, it seems pretty broken for me.
After loading the GUI, it will be inresponsive for a couple of seconds and then crash.
This happens every time.

I wonder what's wrong with my set-up.
I use openSUSE Leap 15.0, Gnome desktop.
All other Gnome tools seem to work just fine.
I put all the output for starting it from terminal here: http://paste.opensuse.org/view//65457179

If anyone can understand why it won't work, I'd be glad to hear!
