I've had brought to my attention that there is a user who submitted a subscription request.  It does not show up in our subscription request list.  When we try to manually add the user to the subscriber's list, we receive an error message saying that there is a pending subscription request.  We can't seem to find this anywhere. 

We've temporarily added them to the non-member list, but that really isn't what we want to do.  Any suggestions? 

This relates to the Wikimedia-L list, and the person who wishes to subscribe has a @wikimedia.org email address.  I don't think this should really make a difference, but any suggestions would be helpful.
