The dash "search your computer and online sources" just spins and hang. It works a few times after each reboot, but then simply stops working. If I select files or applications the dash search works, but the default one "search your computer and online sources" hangs with a spinning wheel. It's been like that since 12.04 I think. 14.04 now and same problem.
I have only apps and files selected under categories and sources.
Any idea what's wrong?
