/usr/sbin/apache: error in loading shared libraries: /usr/lib/php4/apache/xml.so: undefined symbol: php_XML_ParserCreate

Every time that function is used in a php script. This is quite annoying because I use that function on all my pages...

I use the package from debian woody if you need to reproduce it...

I have reported to the debian maintainer but you might want a bugreport as well.
