Lighttpd

The FCGI_PARAMS record misses a length prefix on one of the name-value pairs. This is on Windows with FastCGI set up to communicate over TCP/IP with the app server running locally. Here's a rough print out of the record in question, numbers between #'s represent numeric values of length prefixes (except in a couple of places where ASCII characters appear instead), line breaks inserted for clarity:

The DOCUMENT_ROOT pair above is missing a prefix, resulting in the first two characters being used as a prefix instead.
