  Wrong list then, this should go to xml gnome org

  I really have no idea.
You don't even state the version of libxml2 used, nor the platform ...
this looks like Linux on ia32 ...
Do you use catalogs ? Do you have a /etc/xml/catalog ? 
Do you use threads ? Is the library compiled with thread support ?

  I really don't see how xmlParserGetDirectory() called xmlCatalogResolve()
there is no such call in the code.

  I really don't have enough information to even try to track this down.
