Comment 4 for bug 602526

I don't have a readily available svg file with embedded fonts and an embedded jpg that I can publish here. However tiny changes in the file such as deleting a text node or moving it or resizing stuff seem to alter the error number thrown (but not the text/hint): I just got:
** (inkscape:8979): WARNING **: Called helperfns_read_number with value==null_ptr, this can lead to unexpected behaviour.
