KLV stream not detected

When I run gst-discoverer-1.0 on a file I have, I get:
gst-discoverer-1.0.exe \temp\file.mpg
Analyzing file:///temp/file.mpg
Done discovering file:///temp/file.mpg
Topology:
container: MPEG-2 Transport Stream
video: H.264
Properties:

Seekable: yes

video codec: H.264
If I run gst-discoverer-0.10 on the same file I get:
gst-discoverer-0.10.exe --gst-debug=0 \temp\file.mpg
Analyzing file:///temp/file.mpg
Done discovering file:///temp/file.mpg
Missing plugins

For some reason, on gst-discoverer-1.0 , it fails to detect the KLV stream
for this particular file. However, gst-discoverer-1.0 does detect the KLV
stream on the file John Hanks attached, so it seems the file I have has
some issues (incorrectly encoded or something).
