------- Comment #2 from mrowe at apple.com  2007-07-31 05:23 PDT -------
This was broken in r14258 with the switch to handling plain text files in
WebCore.  DOMImplementation::createDocument checks whether the resource's mime
type should be displayed as a plain text document using:

bool DOMImplementation::isTextMIMEType(const String& mimeType)
{
    if (mimeType == "application/x-javascript" ||
        (mimeType.startsWith("text/") && mimeType != "text/html" &&
         mimeType != "text/xml" && mimeType != "text/xsl"))
        return true;

    return false;
}

MIME types not recognized as text, images, or plugins, are treated as HTML. 
This is clearly not aware of any MIME types registered in WebKit via +[WebView
setMIMETypesShownAsHTML:], so any MIME type starting with "text/" will be
displayed as plain text.  +setMIMETypesShownAsHTML: needs to somehow be hooked
into the logic of DOMImplementation::createDocument.
