Nicolas,

The GDAL: ... messages are debug messages from GDAL.  Normally they should
be turned off though setting the CPL_DEBUG environment variable to ON will
turn them on.  On unix (at least) they go to stderr and would not normally
be returned from a cgi-bin.  Instead they would be logged in the error
logfile for the web server.

The "Content-type: text/html" is supposed to be the first line returned by
a cgi, and indicates to the web server (and the receiving browser) that
what follows is HTML.

So, my suggestion is to review your environment variable settings an unset
CPL_DEBUG.

I haven't been following the rest of your error report so I don't know if this
is the actual problem or unrelated.

Best regards,
