Navmode doesn't exit until application finishes launching

12.04 precise ppa:sil2100. All GPUs.

Whilst in Navmode performing any mouse action is expected to exit navmode.

To reproduce:

1. Press Alt+F1 to enter keynav mode
2. Click on a launcher Icon should exit navmode.

Observation:

If clicking on a launcher icon for an application that takes a little while to launch i.e LibraOffice it can be seen that Navmode is not exited until the application finishes launhing. In other words the Launcher icon remains highlighted during the splash screen and loading of the application.
