gstreamer crashes when opening WMA files

[gregreen]

Totem, Rhythmbox and VLC all crash immediately upon trying to load any WMA audio file. On the command line, Totem throws the following error:

(totem:7461): GStreamer-CRITICAL **: gst_structure_new_empty: assertion 'gst_structure_validate_name (name)' failed
Segmentation fault (core dumped)

Ubuntu release: 14.04

gstreamer version:

  apt-cache policy ubuntu-restricted-extras
  ubuntu-restricted-extras:
    Installed: 60
    Candidate: 60
    Version table:
   *** 60 0
          500 http://us.archive.ubuntu.com/ubuntu/ trusty/multiverse amd64 Packages
          100 /var/lib/dpkg/status

What I expected to happen: The WMA audio files should play.

What happened instead: Every media player that uses gstreamer crashes immediately upon trying to open a WMA audio file.

Status changed to 'Confirmed' because the bug affects multiple users.

Have the same problem, only with WMV.

In my case, when trying to open the properties window in Nautilus over a .mp4 file or if I try to play this file with Totem, I am getting the same error:
"(nautilus:7717): GStreamer-CRITICAL **: gst_structure_new_empty: assertion 'gst_structure_validate_name (name)' failed
Segmentation fault (core dumped)"

I can open the file with VLC though...

I confirm this , whenever I happen to open a .wma file, I get this :

15:06 ~ $ cvlc Videos/Mafikizolo/Mafikizolo/Reunited/01\ Vimba\ Kanjani.wma
VLC media player 2.1.4 Rincewind (revision 2.1.4-0-g2a072be)
[0xe14d68] dummy interface: using the dummy interface module...
Segmentation fault
15:06 ~ $

In my case, VLC is not affected, but Totem, Nautilus, Firefox and Shotwell are. Any video file makes them crash with the following Gstreamer error message:

"GStreamer-CRITICAL **: gst_structure_new_empty: assertion 'gst_structure_validate_name (name)' failed"

I installed all the bad and ugly plugins possible, to no avail.

Is there any activity on solving this bug? As it stands, Ubuntu has a regression that makes it incapable of playing one of the three most common audio codecs.
