These errors started coming up in a previous beta, but have remained even after upgrading to RC1. It seems that all the errors are being generated by threads from a forum one specific forum, but from various threads within that forum.
Sorry about this, finally got my head on straight and deleted an add-on specific to that forum and the errors appear to have vanished.
