Bug#792731: cups: incorrect MIME type on cups.css

[Stephen Kitt <skitt@debian.org>]

Package: cups
Version: 2.0.3-6
Severity: normal

Dear Maintainer,

The web interface is no longer styled on my system, which makes it
somewhat harder to use than normal. Iceweasel tells me

    The stylesheet http://localhost:631/cups.css was not loaded
    because its MIME type, "application/x-csource", is not
    "text/css".

Regards,

Stephen
