Fatal Error On Step 2- Update Table Data

Running Duplicator 0.4.0 and trying to copy a WP site to a GoDaddy account (unfortunately a client requirement).

Database is fine and stage 1 completes successfully. When I proceed with step 2, it comes up with:

server code: 200
status: OK
response:
Fatal error: Cannot call method self::fix_string_callback() or method does not exist in /home/Z/html/Z/installer.php on line 1067

From the installer.log, it has:

VERSION: 0.4.0
PHP: 5.2.17
PHP SAPI: cgi-fcgi
ZIPARCHIVE: true
SERVER: Apache

MYSQL VERSION: 5.0.92-log
