Description:
------------
Calling cacheImageLink() results in a fatal error when image is already cached.

Reproduce code:
---------------
<?php
require_once('Cache/Graphics.php');

$text='Hallo Welt';
$width=100;
$height=50;

$img = imagecreate($width, $height);

$cache = new Cache_Graphics();
$cache->setCacheDir('cache');

$id = $cache->generateID($text.$width.$height.__FILE__,'png');

if (!($link=$cache->getImageLink($id,'png')))
{
if (false == $img)
{
die ("Konnte Bild nicht anlegen");
}
$bg_color = imagecolorallocate($img, 255, 255, 255);
$txt_color = imagecolorallocate($img, 200, 20, 20);
imagestring($img, 3, 5, 5, $text, $txt_color);
$link = $cache->cacheImageLink($id,&$img,'gif');
}

echo "<a href='$link[0]' />";
?>

Actual result:
--------------
Notice: unserialize() [function.unserialize]: Error at offset 0 of 3 bytes in /usr/local/php/pear/Cache/Container.php on line 406

Fatal error: Call to undefined function isExpired() in /usr/local/php/pear/Cache/Graphics.php on line 294
