Wrong errormessage when deleting default relationship

I recently added a default relationship on page ?q=admin/user/relationships/defaults/add, specifying a user and a relationship type.

When deleting the default relationship a message is displayed with the string Default relationship %relationship of %name has been deleted.. Both variables contained the relationship type, none contained the user name. The error is within %name which does no contain the name.

Unfortunately I'm not a programmer, so I can't help to fix the code.
