I had no clue from the exception and the callstack about what could go wrong but I was lucky that I knew what were my last changes in the code so I just started to review and rollback them.

The error itself was quite evident, too bad it only resulted in that runtime exception.
We use a master page file which has a codebehind class also. A property however that is used in the master page as an inline code (<% =MyProperty %>) was declared private static in the codebehind (copy-paste error).
After changing the declaration to public the exception was gone.

Probably many issues may result in that exception but evidently this is one of them.

    This issue is mark up related, use a working master page or try reverting to a version you know is functional using Sharepoint Designer.
