Original commit message from CVS:
* check/gst/gstplugin.c:
* gst/gstelementfactory.c:
* gst/gstplugin.c:
* gst/gstpluginfeature.c:
* gst/gstregistry.c:
Getting tired of debugging.  Disabled all the unreffing of
plugins and features, which fixes the segfaults, but of
course leaks like crazy.  At least playbin works.
