[Python-modules-team] Bug#742508: python-rgain: collectiongain is unusable

[Christian Marillat]

Package: python-rgain
Version: 1.2-1
Severity: serious

Dear Maintainer,

collectiongain (amd replaygain) doesn't work at all :

Dispatching jobs ...
Now waiting for results ...
Unfortunately, there were some errors:
10cc - The original soundtrack: Calculating Replay Gain information ...
  Musique/10cc/1975 - The original soundtrack/01 - Nuit a Paris, pt. 1- one night in Paris-pt. 2- the same night in Paris.mp3:
Error while calculating gain - GST error: Your GStreamer installation is missing a plug-in. (gstdecodebin2.c(3928): gst_decode_bin_expose (): /GstPipeline:pipeline0/GstDecodeBin:decbin:
no suitable plugins found)

10cc - How dare you: Calculating Replay Gain information ...
  Musique/10cc/1976 - How dare you/07 - Rock 'n roll lullaby.mp3:

0 successful, 3 failed.
All finished.

I don't know how to debug that. The --help-gst return nothing.
