Please describe the problem:
Screencasting is described here: http://live.gnome.org/GnomeShell/Features#screencast-recording

GNOME Shell has a built-in feature that allows video recording of the desktop activity. This makes it easy to create high quality screencasts describing the current state of GNOME Shell, but also enables users to make screencasts of their desktop or any particular program. In the future, this feature can be used by some programs for performing usability studies.

Control+Shift+Alt+R keybinding starts and stops the recording. A red circle is displayed in the bottom right corner of the screen when the recording is in progress. After the recording is finished, a file named 'shell-%d%u-%c.ogg' is saved in the home directory. In the filename, %d is the date, %u is a string that makes the filename unique, and %c is a counter that is incremented each time a recording is made within a single gnome-shell session. 

This does not seem to work at all at the moment.  If this is incomplete, suggest updating page to note that it's work in progress.

Steps to reproduce:
1. In a workspace or overlay mode, press Ctrl-Shift-Alt-R
2. No red circle appears
3. No file is saved to the home directory


Actual results:
No visible consequences.

Expected results:
A screencast should start, and red circle appear.

Does this happen every time?
Seems to.
