Binary package hint: totem-gstreamer-firefox-plugin

This issue with an x86 install of Ubuntu Hardy Heron and Firefox 3b5.
The issue is with Totem's browser plugin (libtotem-complex) interfering
with RealPlayer's Mozilla plugin (nphelix.so):

The packaging of Firefox plugins from my install is such that the
plugins are picked up from /usr/lib/xulrunner-addons/plugins (not sure
why this is the case). One of those plugins is the following

* libtotem-complex-plugin.so

>From http://svn.gnome.org/viewvc/totem/trunk/browser-plugin/README
.browser-plugin?view=markup, the complex plugin for Totem handles
"audio/x-pn-realaudio". From my experience this causes two problems:

1. The complex plugin along with the other default installation settings
/ choices for Ubuntu 8.04 results in RTSP content not playing. Please
see attached script/log for more information as to what happens when I
try to play content from this test page:
http://helixqa.helixcommunity.org/HC_JSAPI/index.php

The key issue is ** Message: IsSchemeSupported scheme 'rtsp': no but I
have gstreamer0.10-plugins-good installed (not sure if anything else is
required for RTSP playback)

2. The second and more annoying issue is that this plugin interferes
with RealPlayer's mozilla plugin (nphelix.so). When RealPlayer is
installed and configured, this results in Firefox picking up both
libtotem-complex-plugin.so and nphelix.so for the same MIME type,
Firefox prioritizes handling of audio/x-pn-realaudio to the Totem
complex plugin and as a result playback doesn't happen (see issue 1
above). The workaround is to navigate to  the directory  where Firefox
picks up its plugins from (/usr/lib/xulrunner-addons/plugins in this
case) and remove references/soft links to the totem complex plugin.

Doing that enables Firefox to turn over the mimetype handling to
RealPlayer's plugin and all works as expected.

The problem here is the default Totem installation / configuration
doesn't work for RTSP and worse RealPlayer's plugin is overridden. I am
not sure how Firefox prioritizes handling of MIME types when it finds
multiple plugins that can handle the same type but I do know for a fact
that in Fedora 9 a similar situation ends in RealPlayer handling the
audio/x-pn-realaudio every single time.

Gstreamer plugins version: gstreamer0.10-plugins-good
RealPlayer: RealPlayer 11 GOLD (11.0.0.4028)
Totem:  2.22.1
