call_user_func_array Problem with PHP 5.3.*

[juliancc]

The second parameter in call_user_func_array MUST be an array but only since PHP 5.3 they started to enforce this.
http://us2.php.net/manual/en/function.ca...-array.php

In the plugin_functions.php file, the exec_filter is giving me errors because the $data parameter is a string.

This needs to be address in order for plugins to be compatible when installing GS in boxes that are running PHP 5.3.*

Thanks.
