[XML_Serializer] Array to string conversion on 496

In trying to dump my db to an XML file using the Serializer, I'd received this comment for each row/entry iteration in my db: PHP Notice: Array to string conversion in name/pear/lib/XML/Serializer.php on line 496 I checked the Serializer.php at line 496: [code] if ((string)$tag["content"] == '') { $tag["content"] = ''; } [/code] And it looks like a simple 'check if blank and set to blank' statement. Any idea why this line would be kicking back errors. None of my db fields have empty elements, so each node created should have some value. I checked the archives and someone working with QuickHTML had mentioned an outdated package was the problem. I'm currently running: PEAR 1.3.1 stable PHPUnit 1.0.1 stable XML_Parser 1.1.0 stable XML_RPC 1.1.0 stable XML_Serializer 0.9.2 beta XML_Util 0.5.2 stable Any insights? Cheers, Lincoln
