Gstreamer "filesrc" plugin missing to interact with VLC in Fedora/Centos/Ubuntu? Before it was available

This are installed in my box Fedora 12. And Rpmfusion repository. But still it does not allow me to use filesrc plugin. How can i get that? Note: In my other old Fedora box GST running with filesrc, from those default repositories. I am trying to use the filesrc to load a simple file and test it with VLC in Common Linux distros, but it does not work. This following test is already in a new Fedora 12 (same happen with other distros too).

$gst-inspect filesrc
No such element or plugin 'filesrc'

Solved: by following this discussion: Tim Philipp Muller

Problem (for me it happened for filesrc/audioconvert):
$ gst-inspect filesrc
No such element or plugin 'filesrc'

Step 1:
$ gst-inspect -b

Blacklisted files:
  libgstpython.so
  libgstcoreelements.so

Total count: 2 blacklisted files


Step 2:
$ rm ~/.gstreamer-0.10/registry*
rm: remove regular file `/root/.gstreamer-0.10/registry.i386.bin'? y
$ gst-inspect /usr/lib/gstreamer-0.10/libgstcore
$ gst-inspect /usr/lib/gstreamer-0.10/libgstcorelibgstcoreelements.so
No such element or plugin '/usr/lib/gstreamer-0.10/libgstcorelibgstcoreelements.so'

Step 3: suddently it works, just doing Step 1 and Step 2

Not sure how it is possible for you to not have the filesrc element, it is part of the corelements.so file, so if its missing so should a lot of other core functionality. Here is an output of my gst-inspect command on FC14:
