On further investigation, it seems that what's happening is this:
 * User selects a block of messages to move that is larger than some
   internal limit.
 * As the move process proceeds, the messages are marked deleted from
   the origin folder, but have not yet been copied to the destination.
 * The move fails with no notice.
 * The original state of messages in the origin folder is not restored,
   so the messages remain invisible in that client.
