mpDris2 crashes on startup

[sbuller]

mpDris2 has been running long enough that I didn't even remember what it was when my media keys stopped working...

I got it working again by clearing my playlist in mpd before re-running mpDris2. Looking a bit further into it, it seems I've got some ogg files that cause trouble. 02-So Far.ogg: Audio file with ID3 version 2.3.0, contains:Ogg data, Vorbis audio, stereo, 44100 Hz, ~224000 bps, created by: Xiph.Org libVorbis I

Switching to a different song before launch avoids trouble, and mpDris2 handles the problem files fine once it's running. So, no longer an issue for me, but a reproducible crash on startup.

This is mpDris2 version 0.7 on Fedora 28.
