> After a blond transfer to a destination that then hangs up, the Local;1 channel would suffer a reference leak.  This was due to blond_nonfinal_enter() resetting the props->transfer_target to NULL as it unref'd the channel for itself, later preventing the attended_transfer_properties_destructor() from releasing it's own reference, which was inherited during ast_bridge_impart with INDEPDENDENT.
