Ubuntu One data syncing prevents shutdown

What happens:

– Sync datas with the UbuntuOne-Client
– While Ubuntu One is synchronizing your datas, press the shutdown button at the top on the right of your screen.
– A small frame appears. "Ubuntu One is still synchronizing your data" (or something like that). You can select "Cancel" "Suspend" or "Shutdown"
– If you click on "Shutdown" in the frame, nothing happens. (You have to select the shutdown button at the top on the right of your screen again to shutdown your computer)

What I expect to happen:

– I expect that the computer to shutdown if I select "Shutdown" in the frame.
