Totem-gstreamer crashes Firefox

Hi,

Every time I encounter a page with a video in, either
a) the embedded totem freezes the whole firefox
b) an error pops out stating that Totem can't play fd://0, and firefox crashes
as soon as the window/tab is closed.

ii firefox 1.0.7-0ubuntu20
lightweight web browser based on Mozilla
ii firefox-gnome-support 1.0.7-0ubuntu20
Support for Gnome in Mozilla Firefox
ii mozilla-firefox-locale-en-gb 1.0.4lang20050515-1ubuntu3
Mozilla Firefox English language/region pack
ii libtotem-plparser0 1.2.0-0ubuntu3
Totem Playlist Parser library - runtime vers
ii totem 1.2.0-0ubuntu3
A simple media player for the Gnome desktop
ii totem-gstreamer 1.2.0-0ubuntu3
A simple media player for the Gnome desktop

I'll attach the gdb session.

In the mean time I found that "rm
/usr/lib/mozilla-firefox/plugins/libtotem_mozilla.*"
was the only viable way of surfing without getting an occasionnal crash.
