After upgrading to version 1.5.5 (this occurs with 1.5.5, the daily build, and git master on Ubuntu Karmic), when I listen to Last.FM stations the first two tracks play fine, but when the second one ends it gets the dreaded "red X" and playback stops. The error message that displays in the terminal is: GStreamer resource error: OpenRead. After this, if I manually start the third track by double clicking it, the track plays, but the track information, cover art, context pane, etc. all continue to display the data from the second track. When the fourth track plays, the track information updates, but as soon as the track finishes it gets the red X and the GStreamer error. The pattern keeps repeating every two tracks. This appears to only be happening when listening to Last.FM. Local tracks seem to play fine.
