If typing the command 'service cgmanager status | grep -i active' in the terminal does not who a line containing "active (running)" then this problem is caused by the control group manager not being installed or configured correctly. That manager is used by upstart to run apps in a confined space (yes, even on the desktop). There is a known problem in which this software is not being installed or configured correctly.
If this problem is occurring for you, please issue the above command and check the output.
