Alright, I fixed the mpris problem. Here's how:
Now, I have all my covers showing, and they show in the indicator (so on my phone, the lock screen and pull down menu).
- Install gmusicbrowser_1.1.99.1+1516;
- Go to /usr/share/gmusicbrowser/plugins, and copy mpris2.pm into a temp directory;
- Downgrade to gmusicbrowser_1.1.99.1+1514;
- copy mpris2.pm from your temp directory into /usr/share/gmusicbrowser/plugins, overwriting the version that's there.
