Switching quodlibet from xine-lib to gstreamer (with the gstreamer use-flag) breaks all audio playback in quodlibet. Reproducible: Always Steps to Reproduce: 1. Install quodlibet USE="-gstreamer" 2. Use quodlibet to play music 3. Re-emerge quodlibet USE="gstreamer" 4. Remove xine-lib Actual Results: quodlibet starts but fails to play any music "E: Invalid audio backend. The audio backend 'xinebe' is not installed." Expected Results: quodlibet starts and plays music through gstreamer Re-emerge of quodlibet and related packages and revdep-rebuild do nothing. Workaround: delete ~/.quodlibet, at which point it runs as expected, but all setting are obviously gone. quodlibet-plugins not installed on this system.
Not a bug. This is really a setting left for the user in ~/.quodlibet/config
