perl contrib/bz_webservice_demo.pl --uri http://bugzilla.example.com/xmlrpc.cgit always errs out with 500 Error for Bugzilla.version.
error.log show that
xmlrpc.cgi: Can't use an undefined value as a subroutine reference at lib/SOAP/Transport/HTTP.pm line 384
If I hit another well know server like bugzilla.redhat.com ; it shows version perfectly. That means this server problem and not client related.
Bugzilla version 4.4.6 Uname - Ubuntu 14
