Alarm clock won't close on rc2 kvm build

[Dave Morley]

Once you open alarm clock there appears to be no way to shut it down.

steps to reproduce:

1: locate and activate alarm clock.
2: see it goes into the panel.
3: try and close it.

Expected result: A close or quit tag in the drop down menu.

Actual result: There is no way to close the app.
