Here's the query that is generating this error in QueryableAttribute.ValidateQuery:
<baseurl>?$orderby=Date%20desc&$filter=Date%20ge%20datetime'2012-11-19T00:00:00Z'
This worked until very recent builds.
Comments: we found out this issue as well :(. ODataLib(our dependency) has published a new version (5.2.0 RTM) of their package which has some breaking changes. Unfortunately, nuget downloads the latest version of that package due to the way we had our dependencies mentioned. Please manually uninstall the 5.2.0 version of ODataLib and install 5.2.0-rc1. That should solve this.
