Description gnome 2005-03-31 14:05:53 UTC 
Steps to reproduce:
If necessary I can dig through my archives to find the details but essentially I was using a SAX parser to 
parse SVG files when I encountered this.  (I've changed this since to use a tree in order to support CSS.)
Anyway, the proposed change should be quite safe.

Interesting, yes, a contextual patch is easier to track, but it was
fairly easy, fixed in CVS, thanks !
