base_contact_installer barfs on big data

I'm trying to convert my stuff to trunk...
Installing base_contact module failed saying:

DataError: value too long for type character varying(30)

The culprit is line 56 in base_contact_installer.py:

cr.execute("INSERT into res_partner_contact (name, title, email, first_name, website) (SELECT coalesce(name, 'Noname'), title, email, function , to_char(id, '99999999') from res_partner_address)")

which is trying to cram 64 bytes into 30 with the name field.

The solution is to change the field lengths in res_partner_contact class so they match the corresponding field lengths in res_partner_address.
