Dash finds no applications

[Otus]

After upgrade from raring to saucy, the dash doesn't return any application results.

If I search in dash home, it gives me only files and folders if I look for 'firefox' or 'terminal'. If I go to the applications lens, it says "Sorry, there is nothing that matches your search." even if I type in no text.

Restarting unity or logging out did not fix this, but a couple of reboots later it's gone.

Status changed to 'Confirmed' because the bug affects multiple users.
