I've had a similar problem, this time with an exception in next():

class MyIterator implements Iterator
{
        function rewind() {}
        function next() { throw new Exception('next()'); }
        function valid() { return true; }
        function current() { return 'test'; }
        function key() { return 'test'; }
}

try {
        foreach (new MyIterator() as $x => $y) {
                // do something
        }
} catch (Exception $e) {
        echo "{$e->getMessage()}\n";
}

--- result ---
Fatal error: Couldn't execute method MyIterator::valid in Unknown on
line 0

--- version ---
PHP 5.0.4 (cli) on Linux (Zend Engine v2.0.4-dev)

Description:
------------
It's seems there is not correctly processed exception from current()
and script ends up with fatal error.

Reproduce code:
---------------
class Test implements Iterator {

    public $arr = array();

    public function rewind()    { return reset($this->arr); }
    public function current()   { throw new Exception(); }
    public function key()       { return key($this->arr); }
    public function next()      { return next($this->arr); }
    public function valid()     { return (current($this->arr) !==
false); }
}

$t = new Test();
$t->arr =  array(1, 2, 3);

try {
    foreach ($t as $v) {
        ; // do something
    }
} catch (Exception $e) {
    ; // handle exception
}


Actual result:
--------------
Fatal error: Couldn't execute method Test::key in Unknown on line 0
