> The problem comes from the borrowernumber for new registrants (who haven't been added to the borrowers table yet) being 0 and the query on line 591 of Letters.pm:

($table eq 'borrower_modifications') ? "SELECT * FROM $table WHERE
borrowernumber = ? OR verification_token = ?

Since all new, unverified borrowers have the same borrower number, the Boolean
expression to match on always matches on the borrower # and doesn't look at the
token.  Since, in the detault notice, the only field used in the letter
OPAC_REG_VERIFY is the token, it's not immediately obvious that it grabbed the
wrong record from the table.  

A workaround, which does not appear to impact any other is to alter the query
to ensure the token is checked if the borrower number is 0.  There is probably
a better way than this, but it as worked for me:

($table eq 'borrower_modifications') ? "SELECT * FROM $table WHERE
(borrowernumber = 0 OR borrowernumber = ?) AND verification_token =?"

I'm not familiar with how to propose a patch properly, but this is a small
change in a single line of a module, so I thought I should share.  If this
should have gone in the comments, sorry, I'm new to all this.
