Dash: first-use text entry does not work until Alt-F2 version is used

Bug Description

Quite often, if I press <Super> this shows the Dash, but no text input works. This situation continues, regardless of Dash opening or closing, until the alternative "Run Commandline" Dash is opened with Alt-F2. After this, text entry into the dash works again.

1. <Super> to open Dash
2. Type some text (nothing happens)
3. Repeat 1-2 (still nothing happens)
4. Alt-F2, Alt-F2 (alternative Dash shows)
5. <Super> to open Dash
6. Type some text (text is displayed)

I've seen this too, it's because of focus being screwed up.

This bug was fixed in the package unity - 3.6.6-0ubuntu1
