[LAD] Ubuntu: gstreamer1.0 MP3 playback broken?

Hi! Any Ubuntu users around, "quantal" or "raring" release? If so, could you test if your gstreamer1.0 installation can play MP3s? Recipe: 1. Install everything with gstreamer1.0* in its name, maybe $ sudo apt-get install gstreamer1.0* does the trick If you want finer control, I guess gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools is the proper set of packages. 2. Run the pipeline: $ gst-launch-1.0 uridecodebin uri=file:///path/to/foo.mp3 ! fakesink Instead of "fakesink", you can also try "autoaudiosink" or the even more complex "audioconvert ! audioresample ! jackaudiosink", but that's actually not the question. In the good case, it looks like this: adi@chopin:~$ gst-launch-1.0 uridecodebin uri=file:///tmp/foo.mp3 ! fakesink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 2085409390 ns. Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... In the bad case, you'll get error messages about codecs or a pipeline that doesn't want to preroll. Any feedback would be highly appreciated, it'd save me from installing Ubuntu into a VM. ;) TIA PS: Feel free to file bug reports if it's really broken.
