Failure synchronizing builds from RTC to RQM

We have several project areas with automated builds in RTC 2.0.0.2 (ifix1). Our automated builds are a mix of RTC/Build forge integrations and Jazz build engines.
All but one project areas can synchronize builds with RQM 2.0.1.1 ifix 1. When the problematic Project Area is set to synchronize some builds are imported into RQM but then we get the following exception.

This project area has quite a lot of build results and I would like to identify the offending build result data to identify a means of correcting this integration. Any suggestions as to how I can further debug this error?
