Fatal error on creating consignment for pickup point

[alexroosenstein]

When creating a consignment and supplying it with an address of a pickup point the following fatal error occurs. For reproduction purposes, the address apparently belongs to "De Kade Post". I am using an older version of this library, but the relevant code seems identical to the current version.
