GStreamer General Resource Error

Rhythmbox seemed unhappy with some of my incoming podcasts, quietly refusing to import them with the note: GStreamer encountered a general resource error.

This Ubuntu forum thread suggested removing the gstreamer0.10-fluendo-mp3 package in favor of letting gstreamer0.10-plugins-bad, or in my case gstreamer0.10-plugins-really-bad from debian-multimedia.org. Now those files import just fine. Among the regular offenders were TalkCrunch, Drunk and Retired, and RedMonk Radio.
