[Chicken-users] example.scm from FastCGI egg

[Daniil]

Good day to all Chicken hackers!

I have troubles running example.scm from fastcgi egg
(http://paste.call-cc.org/paste?id=14fbe84f26a8b239986bbc70e856aa57fe35c410).
Here's my NGinx config part, where I access FastCGI:
location ~ /balls/
 {
        fastcgi_pass 127.0.0.1:8080;
        fastcgi_index index.jpg;
        include fastcgi_params;
 }

However, when I try to access a webpage I get a 502 error and `csi
example.scm' produces the following output:


Error: Value of HTTP_CONTENT_LENGTH or CONTENT_LENGTH is not an integer!

        Call history:

        ##sys#peek-c-string
        env287
        fastcgi#fcgx-get-param
        ##sys#make-c-string
        ##sys#peek-c-string
        string->number
        make-property-condition
        abort                   <--

Can somebody please point me to the problem?
Cheers.
