Bug#733911: www.debian.org: Debian Logo svg is unable to be opened in inkscape

[Noah Swartz <swartzcr@gmail.com>]

Package: www.debian.org
Severity: normal

Dear Maintainer,
I downloaded the debain svg logo from www.debian.org/logos in the hopes of printing it using a viny; cutter
When I tried to open it in inkscape I got the following error:
(inkscape:7093): Gtk-CRITICAL **: IA__gtk_widget_get_visible: assertion `GTK_IS_WIDGET (widget)' failed
/home/swartzcr/Documents/ccc/test.svg:18: namespace warning : xmlns: URI &ns_svg; is not absolute

             ^
     /home/swartzcr/Documents/ccc/test.svg:22: namespace warning : xmlns: URI &ns_vars; is not absolute

    /home/swartzcr/Documents/ccc/test.svg:27: namespace warning : xmlns: URI &ns_sfw; is not absolute
    <sfw  xmlns="&ns_sfw;">
which I fixed by removing the line:
18: xmlns="&ns_svg;" xmlns:xlink="&ns_xlink;" xmlns:a="http://ns.adobe.com/AdobeSVGViewerExtensions/3.0/";
It seems that this is formatted in some incorrect way to prevent inkscape from opening the file.
removing the line allows the file to be opened in inkscape, but still ouputs the errors:

		<variableSets  xmlns="&ns_vars;">

but allows for editing.
