The problem appears to be that the parsed XML contains namespace information in the tags (e.g. '{http://www.w3.org/2000/svg}') See also bug #195052.
I've attached a patch that fixes the problem for me (on debian unstable). I haven't tested it on anything else. The patch also filters out the copyright line output by pstoedit, so that the latex effect will give a warning dialog only on actual errors (currently it does so every time it's run).
