Live session froze while using Dash menu

[Øystein Steffensen-Alværvik]

System froze completely while browsing through applications in Dash menu - I clicked on "Dash plugins - Applications". Responded to nothing. Had to reboot. Yakkety daily live session 310816, iso md5 checked and usb drive checked before boot. Could not reproduce.
