Comment 2 for bug 1121395

it appears that this came from some software that uses different conventions than current Inkscape when specifying arcs. It had some negative radii in the file. I've edited the arcs so that they show up.
The font face in this file has been embedded and is apparently not being used as far as I can tell. You may need to install the font RotisSemiSans on your machine to see if this helps.
