This is not new at all, this is something old and the bug's date proves that. Yes, it is still happening only when you have mounted some partitions while you are on the LiveCD (Try ... without installation) and it should never be shown or appeared while choosing "Install ..." so it is just on the LiveCD/LiveUSB mode.
It usually happens to me on the Partitions Window (I always choose Something else) but as far as I remember, I think it happened on other steps but not quite sure about that and I am very positive it appeared on the Partitioning Step.
