Fabio,
The bug is triggered by running out of available inotify watches. Depending on your setup (number of files in Ubuntu One, size of music collection, etc) it may take a while before triggering this bug.
If you have manually increased the number of inotify watches to a reasonnable value, you shouldn't run into that bug at all.
I would mark this bug as duplicate of #879902 , but I'm not sure it's the correct thing to do so I'm just putting it in confirmed.
