Description:
------------
$this->insecure = new Imagick("file.tiff");
$this->originalhash = hash('md5', $this->insecure->getimageblob());
$this->originalhash is always different, but file.tiff is always the
same.
Test script:
---------------
$ob = new Imagick("file.tiff");
$hash = hash('md5', $ob->getimageblob());
