I finally managed to figure out the cause of my problem:  I am using
LANG="en_DK.UTF-8".  It seems this gives the XML parser trouble when
parsing the style file, I'm guessing it starts expecting ',' as decimal
point instead of '.' which causes the mark shapes to be improperly
parsed.  Unsetting the LANG variable fixes it.

It would be nice if I could use IPE without having to unset LANG though.
