here's how to fix the SVG: 1) apt-get install libxml2-utils sgml-data 2) xmllint --noent openlogo.svg > openlogo-fixed.svg (Yes it's "noent", not to be confused with "nonet".) 3) Optionally, remove the DTD declaration from the resulting file.
The last two steps could be merged into one: xmllint --dropdtd --noent openlogo.svg > openlogo-fixed.svg -- Jakub Wilk
