This bug has been reported here: https://bugzilla.ubuntu.com/1453

"Right click on a mp3 file, choose properties, click on the Audio/Video tab.

You will get an error message saying:

"There was an error trying to create the view named 'Audio/Video': System
exception: IDL:omg.org/CORBA/COMM_FAILURE:1.0"

Starting on a terminal:
/usr/lib/totem/totem-properties-page

and then firing the properties of an mp3 file, you get on the terminal:
(totem-properties-page:6612): GLib-GObject-CRITICAL **: file gtype.c: line 2254
(g_type_register_static): assertion `parent_type > 0' failed

(totem-properties-page:6612): GLib-GObject-CRITICAL **: file gtype.c: line 2254
(g_type_register_static): assertion `parent_type > 0' failed

(totem-properties-page:6612): GLib-GObject-CRITICAL **: file gobject.c: line 819

Segmentation fault"


Happens here too (but no segfault), totem 0.99.20, gstreamer 0.8.7, gst-plugins
0.8.5
