totem-2.27.2-6.fc12.x86_64 -- When a user attempts to play an MP3 file without support, totem delivers a "Internal data flow error", and refuses to proceed. Ogg Vorbis works fine.
Error message: ** Message: Error: Internal data flow error. gstbasesrc.c(2378): gst_base_src_loop (): /GstPlayBin2:play/GstURIDecodeBin:uridecodebin0/GstFileSrc:source: streaming task paused, reason not-linked (-1)
