Description:
------------
Calls to Imagick::cropImage fail. I've tried the OS-shipped 
imagick.so and I've 
also installed it via pecl (after uninstalling the OS-shipped 
one).

Reproduce code:
---------------
<?php

$image = new Imagick('mario-1-1.gif');
$image->cropImage(8,8,0,0);

Expected result:
----------------
I expect no segmentation fault.

Actual result:
--------------
