Daniel, AFAIK, the status in the GUI is the status of a VM snapshot. In that case, this is documentation bug, if anything.

Can you please confirm/refure?

Indeed, broken VM snapshot is merely an engine terminology; i.e. vdsm isn't aware (and shouldn't be) of this status. In any case, broken status should be removed as part of bug 1056935.
