[libxml-devel] xpath.find fix

[Dan Janowski]

The SVN repository now includes version 0.5.2.2 (as of #212) that  
fixes a major problem with .find expressions which return non-nodeset  
results like a boolean, string or number. This seems to fix the only  
remaining memory fault (segv) that I am aware of.

The only two outstanding service issues which stand between here and  
the next release is:

1. correct find operation with namespaces
2. wall-clock delay when using Reader
