Unity Dash stops responding to key presses if you move too quickly with arrow keys

[nicedanmonkey]

Steps to reproduce bug:
-Press Super Key
-Type "usb"
-Before the dash loads the "Files and Folders" section press down once with the arrow key.
-After the "Files and Folders" section loads my system stops responding to keyboard inputs. I can't click escape, arrow keys, enter... etc.

If you can make it down to the very bottom of the dash where the small icons for Applications, Files and Folders, Music and Photos are then the keys do not freeze up for some reason. Also if you don't try to move at all with the arrow keys until everything is loaded then the keys do not freeze up either.
