I don't see how this was generated. You call xmlAddChild() but
I have no idea what parent and cur are, what they contain, how they
were created. I really can't process this without further informations.
I would need the value for the pointers of cur->content, cur,
cur->properties, cur->doc, cur->doc->dict in the called xmlNodeAddContentLen()
Back to normal priority and severity untill further informations too.

smitten, add an example code/file please
Comment 3 Brent Smith (smitten) 2006-07-04 16:28:10 UTC 
I'm sure this was my fault and I can't reproduce anymore, so I'll close it.
