TFS, Reporting Server & Sharepoint

Does your interface complain about IReportViewerMessage? I searched whole-over my web.config files to identify and finally I found it in my Sharepoint Server web.config file:



I didn't do much else then to comment this line and tried to run it again. Ohh good, the good thing is:

• Everything worked as expected
• No errors are getting displayed on the websites or Event Log

The bad thing is:

• Why the hell this happens?

Since 3 day's i haven't experienced any difficulties with this solution but who knows when it ill come.
