unity-place-files doesn't update results in dash while typing

[Migas]

When I press super+f to find a file there is a list of recently opened files.
But as I start to type, for each letter the progress circle goes round a little, but then it stops, and the results don't even flicker, whatever I write.
In the dash itself (press super only) there isn't even a file section, just the app section is shown.

Can confirm non-intended behaviour of the search function. Have a file on my desktop, searching its name doesn't result in the file being shown. (Note that the RHS drop down is on "All Files")

Reproduce by:
cd ~/Desktop
touch test.cpp
<super-f> test.cpp

Slight strange settings:
1. I'm logging into Ubuntu Classic, and running "unity" from a terminal.
2. I have the system tuned for audio performance, ie: changed the "inotify" parameter like so: fs.inotify.max_user_watches = 524288 (afaik this is to do with file-system monitoring, perhaps it is irrelevant)

For the record; i don't think that a file you 'touch' should show up in the files lens. That said I acknowledge that there are files which would be sensible to show that we don't show. This is the topic of bug 646724.
