Comment 10 for bug 195052

Indeed the script does not like the namespace to be prepended to each tag. I added some code to remove the namespace from the input tags before adding them to the group, and the LaTeX formula appears correctly. I know almost nothing about Python, so there must be a better way to do it, but it now works with the patch included. My version of pstoedit doesn't support the '-quiet' argument by the way, so I did not include Tom's idea.
