Default state/province not working

In the "Administer / Localization / Languages, Currency, Locations" screen you can choose a default Country and State Province for contact address fields. When choosing a country AND state, only the country is defaulted when creating a new address.

To reproduce:

• set default country = United States, default state = California in the above settings screen
• go to any contact, create a new address for this contact
• the country field will be pre-filled with United States, but not the state
• save the address, the country is correctly saved but the state is still empty
