chaining api.phone.create generates multiple duplicate phone numbers

I have written a simplified front end for contact data entry in our church. Everything was working well until I updated civicrm to 4.3.5 from 4.2.6. Now, my frontend code generates multiple distinct phone number entries.

Currently, I'm assembling household data, contact data, and location data in one large array using api chaining syntax. I send all the data using the civicrm_api() wrapper. I combine it all so that there are fewer server hits, and because I want to trust the api to do it's job.

However, chaining always seemed to create duplicates with activities and certain custom fields, so I separated them out. Now, however, it's creating MANY duplicates of the phone records. Here's some sample data just before calling civicrm_api(). Note that the Household exists in the database already (it has a contact id) as does the Individual (also has a contact id), but in this case, the Individual Home Phone number is new:

[code]
Array
(
[contact_id] => 8481
[household_name] => Household 1
[contact_type] => Household
[api.phone.create] => Array
(
[0] => Array
(
[phone] => 111-111-1111
[id] => 4705
[location_type_id] => 1
[phone_type_id] => 1
[contact_id] => 8481
)

[1] => Array
(
[phone] => 222-222-2222
[id] => 4706
[location_type_id] => 1
[phone_type_id] => 2
[contact_id] => 8481
)

)

[api.email.create] => Array
(
[0] => Array
(
[email] => a@b.c
[id] => 3663
[location_type_id] => 1
[contact_id] => 8481
)
)
[api.contact.create] => Array
(
[0] => Array
(
[contact_type] => Individual
[first_name] => Person
[last_name] => Household 1
[contact_id] => 8482
[api.phone.create] => Array
(
[0] => Array
(
[phone] => 333-333-3333
[location_type_id] => 1
[phone_type_id] => 1
[contact_id] => 8482
[is_primary] => 1
)
)
[api.note.create] => Array
(
[entity_table] => civicrm_contact
[note] => MODIFIED WITH API ON Tue, 20 Aug 2013 15:43:55 -0400
[entity_id] => 8482
[contact_id] => 1
[subject] => API NOTE
)
[api.relationship.create] => Array
(
[contact_id_a] => 8482
[contact_id_b] => 8481
[relationship_type_id] => 7
[is_active] => 1
[is_permission_a_b] => 0
[is_permission_b_a] => 1
[id] => 3207
)
)
)
[version] => 3
)
[/code]

Then immediately after calling civicrm_api() with this array, I get the following response:

Everything looks good right?
