It's working ok with proposed package .
If anyone wants to update only the owncloud-client package (and dependencies) you must first enable proposed repo (Unity Settings > Software & Updates > Last tab) and reload package info.
Then force the upgrade only of owncloud-client and needed libraries by: sudo apt-get install owncloud-client
You can now safely disable proposed repo waiting for a new update on main Universe updates repo.
