Same issue.
Duplicator version 0.5.2, WordPress 3.9.0 on IIS7 (Win7 32bit)
Created dump (SQL file in package) includes wrong rows:
INSERT INTO wp_options VALUES(“”, “”, “”, “”);
Same installation, no change in any settings (WP, IIS, PHP, MySQL) but duplicator 0.5.3 – SQL file is OK:
INSERT INTO wp_options VALUES(“3”, “blogdescription”, “Just another WordPress site”, “yes”);
INSERT INTO wp_options VALUES(“4”, “users_can_register”, “0”, “yes”);
etc…
