Bug Description

When I run scour on that SVG, I get a crash:

scour 0.25

ValueError: too many values to unpack

The SVG is shipped in the gnome-applets-data package, but I attach it here for reference.

Thanks!

This is an exception that's being thrown by the xml.dom Python package, and it has to do with the input file having a space in an URL-typed attribute:

3: <svg
4: xmlns:s="http://inkscape.sourceforge.net/DTD/s odipodi-0.dtd"

URLs can't have spaces, per RFC 3986 <http://www.rfc-editor.org/rfc/rfc3986.txt>

As a workaround for your problem with the file, you may run this command and retry Scour:

sed -i 's/s odipodi-0/sodipodi-0/g' /path/to/gnome-cpu-frequency-applet.svg
