Please describe the problem:
I use Fedora Core 5 and Thomas's gstreamer repository
(http://thomas.apestaart.org/pkg/). Until a few weeks ago, I could play Ogg
Theora videos just fine with totem, but a recent update seems to have broken that.

Steps to reproduce:
1. wget http://www.v2v.cc/~j/theora_testsuite/320x240.ogg
2. totem 320x240.ogg
or try to play any other Ogg Theora video.

Actual results:
Totem prints the following to stdout:
(totem:4839): GStreamer-CRITICAL **: gst_event_new_new_segment: assertion `start
!= -1' failed
and a window pops up with the message:
  An error occurred
  Internal data flow error.

Expected results:
Totem plays the video.

Does this happen every time?
Yes.

Other information:
This is with Fedora Core 5 on an Pentium 4.

The gstreamer packages are from http://thomas.apestaart.org/pkg/ and the
versions are:
gstreamer-0.10.5-0.gst.1.5
gstreamer-plugins-base-0.10.6-0.gst.1.5
gstreamer-plugins-good-0.10.3-0.gst.1.5
gstreamer-plugins-bad-0.10.3-0.gst.1.5
gstreamer-plugins-ugly-0.10.3-0.gst.1.5
totem-1.3.92-1

Totem still plays other file types (I tried mpeg, avi, mp3 and Ogg Vorbis).
