HTTP status codes generally:

    http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html


Slightly more user-friendly descriptive guide:

    http://www.addedbytes.com/for-beginners/http-status-codes/


406 indicates an unacceptable request.

Bumping up your apache debug levels and watching the error log may help,
as could snooping the traffic generating the request (packet/GET
request).
