MailSend error -- "Unable to get users from GAL to select random users"

[William-Rohm]

[1] With one recipient specified, MailSend works as expected.
[2] With RandomRecipients specified, with or without an explicit DistributionList, MailSend returns the above error message and skips mail sending. The complete message is:
