Comment 3 for bug 1194775

Actually, since I've reported this issue, I've investigated it and have found that it is not related to Ubuntu One but that it is another Google Drive bug.

The folders were initially synced by Google Drive with their servers until I completely uninstalled their client and installed the Ubuntu One client on my laptop.

I have discovered that the Google Drive uninstallation process was incorrect and has left some undefined configuration on my system which prevented them from being correctly synced with Ubuntu One client (and probably any other Cloud client).

I have detailed the proof in this thread on Ubuntu Forums: http://ubuntuforums.org/showthread.php?t=2158354

I hope my workaround will help others with this issue until Google solve it someday...
