Notice: Array to string conversion in content_access_get_setting_defaults()

in content_access.module file, i've found a problem with line 267 on function content_access_get_setting_defaults()

    case 'per_node':
      return array();

I'get a Notice: Array to String conversion ....

The fix is returning a boolean instead like this.

    case 'per_node':
      return FALSE;

I' have no time to clone/fix/attach patch. Hope somebody can get this and fix soon.

Cheers!
