Bug#866339: gstreamer1.0-plugins-ugly: fails to play mp3 files

[Martin Bergström]

Package: gstreamer1.0-plugins-ugly
Version: 1.12.1-1
Severity: normal

(I am not confident diagnosing gstreamer issues, so please bear with me.)

Other formats like ogg and flac works fine. Also non-gstreamer players 
can play
mp3 files.

There is an error message in Quod Libet and Totem when attempting to 
play mp3
files. Totem says "MPEG-1 Layer 3 (MP3) decoder is required to play the 
file,
but it is not installed."

gstreamer was recently upgraded to 1.12.1-1. (I think the problem manifested
also in 1.10.4-1 but I might have that wrong.) It worked a couple a 
weeks ago on
this machine running up-to-date "testing".

1.10.4-1 depends on libmad0 but 1.12.1-1 does not.
libmad0 0.15.1b-8 is installed to satisfy dependencies of other packages.

Is there anything else I can do to diagnose or fix this issue?
