Unsupported operand types in system\library\currency.php

Fatal error: Unsupported operand types in D:\www\opencart\system\library\currency.php on line 69

I got this error if I added special prices to some products. Without the specials, I did not have this problem.

I am using version 1.5.1

I didn't touch any of the currency settings, and I really have no idea about what's causing this problem. But this problem is gone after I changed line 69 from:
to:
I am not sure this change will have any side affect or not. And I really want to know the root cause to this problem, and the way to properly fix this. if this is a bug, hope it will be fixed in the future release.

Thanks

Ifso the best thing you could do is go to your table and change this, to this . to prevent any future problem with fetching from the database.

Ah my bad didn't read and also didn't check the database on the type.
