If an SVG image is sent as text/xml rather than image/svg+xml then WebKit+SVG (2005-10-03) will display "image/svg+xml" and nothing else. Viewing the page source correctly displays the contents of the SVG file.
This actually has nothing to do with our SVG support, this is an XML rendering bug.
This appears to be fixed in TOT WebKit.
And still in current ToT (13-7-2006) this seems fixed! IMHO this bug should be closed. Cheers, Rob.
Confirmed working in locally-built r15416.
Mass moving XML DOM bugs to the "DOM" Component.
