hydra.nixos.org server config problem with text/xml

[Vincent Lefevre]

Hi,

When the web browser accepts text/xml, HTTP requests fail.
For instance:

The HTML versions are OK.

Note: there are just examples. My Firefox also accepts other MIME types
but prefers text/xml, and things fail due to that.
