There is ZBX-7665, which looks different, though (IMO).
Harrison, would be good if you retest the proxy with Pre-2.2.4rc1 (stable) downloaded here http://www.zabbix.com/developers.php

Comment by Aleksandrs Saveljevs [ 2014 Jun 09 ]

Note only that you if wish to test the nightly snapshot, you have to wait until the regression in (1) in ZBX-8287 is fixed. Otherwise, a proxy that sends empty item data is pretty useless.

This issue is the same as ZBX-8629. Let's continue the discussion there, because that issue has more information. Closing this one as a duplicate.
