Comment 14 for bug 313587

Running Ubuntu 10.04 Lucid:
ii rhythmbox 0.12.7-0ubuntu5 music player and organizer for GNOME
ii rhythmbox-plugin-cdrecorder 0.12.7-0ubuntu5 burning plugin for rhythmbox music player
ii rhythmbox-plugin-coherence 0.12.7-0ubuntu5 UPnp plugin for rhythmbox music player
ii rhythmbox-plugins 0.12.7-0ubuntu5 plugins for rhythmbox music player
ii rhythmbox-ubuntuone-music-store 0.0.5-0ubuntu1 Ubuntu One Music Store Rhythmbox plugin

I get the described problem (see attachment). There is a related discussion here:
http://ubuntuforums.org/showthread.php?t=1204619 I'll try out the proposed solution and see what happens. My experience of this bug is that it does not seem to be format-related, where I have observed flac files sometimes doing the same thing, and sometimes behaving correctly. I need to do more testing because I have two separate instances at home and at work and haven't had time to get to the bottom of the pattern (if any).
