SVG Viewer doesn't work properly with svg namespace

[vfro]

SVG Viewer doesn't work properly when svg is defined in a separate xml namespace like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg:svg xmlns:svg="http://www.w3.org/2000/svg">
</svg:svg>

Even though this is a perfectly correct xml file, the following error is shown: "Active editor doesn't show a SVG document - no properties to preview."
