Comment 1 for bug 646724

Zeitgeist and unity-place-files are both designed with the specific goal of *not* needing to monitor the home directory recursively. This is a can of worms of titanic proportions.

The best solution would be to have OO push it's changes to ~/.recently-used.xbel in which case Zeitgeist, hence, u-p-f, would pick it up automatically.

But I agree, the current situation is less than ideal.
