File properties - notes - in Nautilus lost after upgrade to Hardy

[element42]

I upgraded to the Hardy RC on Sunday. I've just noticed that the notes I has associated with a lot of my files in Nautilus have just gone. The little star icon is missing, the notes tab is still under file properties (afetr right click), but there's nothing in it!
Some of them were fairly important. Are they gone forever, or hidden somewhere?

Thanks!
