XEmacs works just fine for all xml files I've ever editted--- except for
one. Attempting to open the file causes xemacs to close abruptly.  I've
attached the xml file in question. (Please treat this file as private.)

As far as I can tell, the "Fontifying..." frame shows "Fontifying
csm_macros.xml... (syntactically)", which is then covered by a windows
dialoge box "xemacs has stopped working ...".

XEmacs version: 21.4 (patch 22), Jan 6, 2009
