issue #2291 --> still getting the error in_array() expects parameter 2 to be array, ecc....

[nikto1]

I get it only if I'm "shopping" as a guest and if i have already filled in the fields in the checkout area.
Then i change any custom field to type= checkbox in the admin area, and after that i reload the checkout area/ page in front-end.
It's strange because the code for the checkboxes in
catalog/view/theme/default/template/account/address_form.tpl
and
catalog/view/theme/default/template/checkout/guest.tpl +
catalog/view/theme/default/template/checkout/guest_shipping.tpl
is the same, but in the second and third file i get the errror as described above.

Tested with the newest master-branch.
