Bug in WikiUserNew.php

Hello,

there is a known bug in WikiUserNew.php (release 1.3.14 and CVS 
version). A bug report can be found on sourceforge: 
http://sourceforge.net/tracker/index.php?func=detail&aid=1792652&group_id=6121&atid=106121

Usind phpwiki with php 5.2.x and external authentication produces a loop 
in WikiUserNew.php. The result is an empty page. Trying the same with 
php 4.8 no problem exists.
The loop is between this calls:

              is_subclass_of
            isa
              check_php_version (3x)
              is_object
              get_class
              strtolower (2x)
              is_subclass_of
            get_class
            _DbPassUser->hasHomePage
          _DbPassUser->userExists
            get_class
            strtolower
            check_php_version
            UpgradeUser
              isa
                check_php_version (3x)
                is_object
                get_class
                strtolower (2x)
                is_subclass_of
              isa

Admin authentication works with php 5.2.5 fine. User authentication breaks. 
Our new server cannot be used until this bug is fixed. So i try to ask for help here also.
Thank you, regards Stefan
