Gstreamer 1.0 has missing core elements

Bug Description

I wanted to test gstreamer's pipeline functions in command line using Jono Bacon's tutorial. I thus ran

    gst-launch-1.0 filesrc location=mysong.mp3 ! decodebin ! audioconvert ! alsasink

And this error came up:

   ERROR: pipeline could not be constructed: no element "filesrc".

I dug a little through the google searches, and using gstreamer-inspect1.0, I was able to list all the installed plugins. Amazingly, *none of the coreelements plugins are present*.

Is there a way to fix this? Is there a packet that might have been forgotten in the 13.10-14.04 update process?

PS: I have troubles with *all* the gstreamer-dependent application on my 14.04 install so this is probably related.

Ok, found the fix on an partially related AskUbuntu question. I just had to empty the gst1.0 cache:

    rm -r ~/.cache/gstreamer-1.0

And then everything worked. The Ubuntu update tool maybe screwed up at some point with this.

^ that solution worked for me.

I can't believe that such a basic system functionality can get messed up by user config files!
