The following procedure:
* shutdown syncdaemon (u1sdtool --quit in a terminal)
* backup your shared metadata (tar -cjf share-md.tar.bz2 ~/.local/share/ubuntuone/syncdaemon/vm/shares/)
* remove the shares metadata (rm -rf ~/.local/share/ubuntuone/syncdaemon/vm/shares/*)
* start again syncdaemon (u1sdtool -c)
Fixes the state of UbuntuOne Client (I mean, that it is shown "Synchronization in progress..." instead of "Unknown"), but the synchronization does not actually start.
