Bug Description

Fresh wipe flash of #281 on mako
Added a U1 and 2xGoogle accounts in system settings

Looks like there was a problem with quoting between unity-mir and libupstart-app-launch.

The Exec line from the google webapp is:

Exec=aa-exec-click -p net.launchpad.click-webapps.googleplus_googleplus_6 -- webapp-container --enable-back-forward --webappUrlPatterns=https://plus.google.*/*,https://accounts.google.*/* https://plus.google.com

So it might be asterisks are problematic?
