new install of openerp 7 for windows.

here's what i've done:

imported customers first - no issues. imported contacts for customers, used the customer id as the parent id so they'd be linked - no issues. everything appears to be working correctly, the contacts show up in the customer contacts fields, etc. however, when i try to delete the customer and/or contact, i get an error. if i try to delete just the contact from the customer form, i get the same error when i click save. the error is really long, but here's how it starts:

OpenERP Server Error

Client Traceback (most recent call last): File "C:\Program Files\OpenERP 7.0-20130920-231040\Server\server\openerp\addons\web\http.py", line 204, in dispatch File "C:\Program Files\OpenERP 7.0-20130920-231040\Server\server\openerp\addons\web\controllers\main.py", line 1128, in call_kw

here's what it ends with (after a couple hundred error lines):

RuntimeError: maximum recursion depth exceeded

any idea what's going on here?

tia!

update: i discovered that the only customers this affects are customers that the contact name is the same as the company name... i don't get it...
