[SOLVED]Bad header=No recipient addresses found when trying to register

[smartcall]

Hi,

Thank you for your wonderful product!
I almost finished creating a shop with 200 products. The most important thing to notice is that the shop is in Cyrillic. I tested all the functionality and always registered my test users with Latin names.
The problem occurred to me just today, when I was about to put the shop in production.

And the problem is:
User try to register and enter his first and last name as well as address and city with Cyrillic letters -> Submit -> Internal Server Error
And in server log

malformed header from script. Bad header=No recipient addresses found i: authentication.php

If the same user with the same email address enter his details in English, the registration completes with success.

Not to mention the PDF creation issues, but this is a separate topic.

Prestashop 1.0
php running as fast-cgi

SOLVED with dirty hack.

In classes/Mail.php line 55

from

$to = new Swift_Address($to, $toName);

to

$to = new Swift_Address($to, $to);

Looks like when $toName is not in Latin there is a problem.
