Non catched Exception

[thefunkyjoint]

Hello,

I have the following code that for some reason, is not working. Instead of the exception being catched, i get a PHP fatal error :

try {
$this->query1->filter = 'some invalid filter';
$this->query1->open;
} catch (Exception $e) {
die ('this should happens, but is not');
}

Instead of catching exception and showing the die() string, i get the following error :

PHP Fatal error: Call to undefined method ADODB_Exception::inheritsFrom() in E:\home\vcl\classes.inc.php on line 977

I don't know why ...
