These are truly ancient versions.

mp4mux/qtmux used to be in gst-plugins-bad, and at some point (with -bad
0.10.22 and -good 0.10.29) moved to gst-plugins-good. If you upgraded
just one of those packages (say: -bad) to a newer version, but not
-good, you'd suddenly not have it any longer of course.

But there might be other reasons as well, hard to say without more info.

You could also try removing your registry:

  rm ~/.gstreamer-0.10/registry*

to see if that helps.
