Step 1

Create a contact and add an "Instant Messaging" field. Set the protocol to a custom protocol by typing in it (for example: "None").

If you get this contact via the API, you get something like this:

GET /m8/feeds/contacts/default/full/3f9ffe1d8c52ef93?prettyprint=true HTTP/1.1
Host: www.google.com
Gdata-version: 3.0

        <title>Google Bug</title>
        <link rel='http://schemas.google.com/contacts/2008/rel#photo' type='image/*' href='https://www.google.com/m8/feeds/photos/media/mattias%40piesync.com/3f9ffe1d8c52ef93'/>
        <link rel='self' type='application/atom+xml' href='https://www.google.com/m8/feeds/contacts/mattias%40piesync.com/full/3f9ffe1d8c52ef93'/>
        <link rel='edit' type='application/atom+xml' href='https://www.google.com/m8/feeds/contacts/mattias%40piesync.com/full/3f9ffe1d8c52ef93'/>
        <gd:name>
                <gd:fullName>Google Bug</gd:fullName>
                <gd:givenName>Google</gd:givenName>
                <gd:familyName>Bug</gd:familyName>
        </gd:name>
        <gd:im address='test' protocol='None' rel='http://schemas.google.com/g/2005#other'/>
        <gContact:groupMembershipInfo deleted='false' href='http://www.google.com/m8/feeds/groups/mattias%40piesync.com/base/6'/>
</entry>

So the protocol is set to None.

Step 2

Now try to update the same contact via a batch request, where we just update the family name to "Bug update". This is the request and response:

POST /m8/feeds/contacts/default/full/batch HTTP/1.1
Host: www.google.com
Gdata-version: 3.0

          <gContact:groupMembershipInfo deleted='false' href='http://www.google.com/m8/feeds/groups/mattias%40piesync.com/base/6'/>
  </entry>
</feed>

Response:

</errors>

This results in an error, while only information received from the api was sent back. This is definitely not expected behavior.

When issueing a normal update request (no batch), it works as expected:
