Comment 16 for bug 1041032

Experimental report:
  system: Precise i386
  1. remove gstreamer0.10-plugins-ugly
  2. Open a terminal in unity and type "totem [enter]"
  3. Drag and drop the "Wildlife.wmv" file into the playlist of totem
  4. While starting to play it, totem ask to install the Advanced Streaming Format (ASF) demuxer,
        agree it and go through the install.
  5. The error message pop out, in the terminal it left messages like this:

** Message: Missing plugin: gstreamer|0.10|totem|Advanced Streaming Format (ASF) demuxer|decoder-video/x-ms-asf (Advanced Streaming Format (ASF) demuxer)
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  import gobject._gobject
** Message: Missing plugins installed. Updating plugin registry ...
** Message: Plugin registry updated, trying again.
** Message: Error: No URI set
gstplaybin2.c(3824): setup_next_source (): /GstPlayBin2:play

  6. Click on the play button, the error message will pop out again. And so is the last two lines in the terminal.
  7. Drag and drop the "Wildlife.wmv" file into the playlist again, it make the second item in it.
  8. Double click on the first "Wildlife.wmv" that is already on play, got no result.
  9. Double click on the second "Wildlife.wmv", it goes on normally.

I think restart the playing as a new file with some statement may bypass this issue, though bug could still there.
