RT::Extension::MergeUsers won't merge users

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I have installed RT::Extension::MergeUsers and am attempting to merge
2 users as a test.

I have 2 users:
Username: Foo
Email: foo@sub.example.com

Username: Foo@example.com
Email: foo@example.com

The second was autocreated on submission of a ticket via email if it
matters.

When I attempt to merge either the first into the second or the second
into the first, it fails with “Could not merge Foo into itself”. These
are 2 separate users, but MergeUsers is seeing them as the same user.

Any suggestions as to what the problem is? Is this me tickling some
bad ExternalAuth config along the lines of attr_match_list or attr_map?
