Currency error upgrade 1.9.0.1 to 1.9.2.1

[Digital Daemons]

After upgrade to version 1.9.2.1 via command line everything works fine except "Create new order from admin panel" 

When adding products to the new order there's an error:

PHP Fatal error:  Call to a member function getCode() on a non-object in /public_html/includes/src/Mage_Directory_Model_Currency.php on line 194

We have base currency as MXN and no other addon currency so we:

Added USD as a second Currency with MXN as a base currency and we could now add products

BUT when selecting payment method got the same error as before

Everything was working fine on 1.9.0.1 any ideas? what could be broken

Hi.

Just before the

throw new Exception();

on line 193 of app/code/core/Mage/Directory/Model/Currency.php, can you add in the following

var_dump($toCurrency);

and let's see what that outputs.

Regards,

Thanks for the quick response iweb_smartie

used:  Mage::log('$toCurrency = '.$toCurrency,null,'debug.log',true);

instead of var_dump() 

And I got the following:

DEBUG (7): $toCurrency = false
