Recently I updated SMW to v1.7.0.2. With new SMW browsing "Property:Title" page ("Title" is a user-defined property) causes the PHP warning:

> Warning: array_merge(): Argument #2 is not an array in /var/www/oc.su/MediaWiki-1.18/includes/Sanitizer.php on line 714

When I roll back to SMW r105224, warning disappears, and property page is displayed cleanly.

I temporary added a "if" check:

> static function mergeAttributes( $a, $b ) {
>     $out = array_merge( $a, $b );
>     if ( ! is_array( $b ) ) {
>         throw new Exception( "AAAAAAAAAAAAAAA" );
>     };

and get a callstack:

> Unexpected non-MediaWiki exception encountered, of type "Exception"
exception 'Exception' with message 'AAAAAAAAAAAAAAA' in /var/www/oc.su/MediaWiki-1.18/includes/Sanitizer.php:716

It should help to diagnose the cause of issue.
