when in the files & folders lens clicking on any other folder apart from the home folder doesn't open

[rue]

when I open dash and move to the files and folders lens, clicking on any of the folders doesn't open them.
Clicking on my home folder and it works. Also clicking on files in the files and folders lens seems to work ok.
I upgraded from 11.10 to 12.04 beta 1
