I updated to Saucy this morning, and my computer freaked out mid-way through and I was forced to power it off to get it to respond.

When I restarted it (naturally) didn't work, so I launched a terminal and used apt to continue the install. I wish i remembered what I executed...but I don't.

Now I have my desktop back and everything seems to be working except the Dash. Super-key + typing now just shows me a spinner and nothing.

I've deleted zeitgeist and software center caches, and I've tried to install unity-place-applications, but no effect, because I can't find it...and it doesn't feel like the sort of thing that would be in a separate ppa...:

$ sudo apt-get install unity-place-applications

[sudo] password for cpfohl: 

Reading package lists... Done

Building dependency tree       

Reading state information... Done

E: Unable to locate package unity-place-applications

Any ideas where I can start tracking this down? All the apps are still there, I can launch them with the command line if I know where they are, but the dash just isn't doing anything useful.
