Comment 6 for bug 43464

I have no idea whether it’s Quod Libet or X.org that’s broken here; X.org seems to get the keys properly (i.e., they show up in the keyboard shortcuts selector), so it either does not pass them to Quod Libet or Quod Libet doesn’t know what to do with them.

FWIW, the shortcuts work when Rhythmbox is open (and change the song in Rhythmbox).
