Duplicate Data Source error for brand new, virgin report

I think there may be a fundamental problem with the enteprise gateway.   I have setup a brand new gateway and tried to create a datasource for the following URL's

https://www.google.com.au/?q=1

https://www.google.com.au/?q=2

I can only create a datasource for one of these, not both.   When I try to do both I get a duplicate data source error.   It looks like the enterprise gateway is stripping off the query string when checking for duplicates.

Unfortunately, this is a fairly serious limitation as when using Reporting Services (and most likely other web applications) much of the unique information is contained in the query string.

This has not been a problem in the past so looks like something that has recently been introduced.   Not sure how we get this fixed but I think a lot of other users may also start to have problems.
