The video is misleading. There are possible network configurations where nodes keeping different trust lists will end up partitioned from each other (separate lost closed ledgers). OpenCoin, to my knowledge, has done nothing to fix this as it is a problem inherent in the consensus mechanism they are using. The way you fix it is using some other deterministic method for decentralized consensus... like proof of work.
Do you have a source for that claim? There is no reason why nodes with different trust lists would become partitioned. Even if a majority of the nodes were malicious, all they could do is prevent the honest nodes from reaching consensus. The honest nodes would effectively stop operating, as every ledger confirmed by the malicious group would be marked as unreliable by the honest group.
Yes, it's in the original bitcointalk thread where Ripple.com was announced. A note about your example: it's not a majority of all nodes, it's a majority of your trusted node list. Which is different for every node.
