Description:
------------
Segfault happened on pdf file in identifyImage function.

Please refer on our Fedora bug for more info - 
https://bugzilla.redhat.com/show_bug.cgi?id=638352

It always reproducible. Backtraces also available.

P.S. I actually use php version 5.3.4, but it is not listed 
in your dropdown select.

Reproduce code:
---------------
<?php
$imagick = new Imagick();
$imagick->pingImage('/home/rhollencamp/test.pdf');
$image_info = $imagick->identifyImage();

var_dump($image_info);
?>

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

Looking at the backtrace the crash happens inside ImageMagick. I'll take a proper look later

Please note also ImageMagick standalone command work 
perfectly on this file:
$ identify test.pdf
test.pdf PDF 1200x800 1200x800+0+0 16-bit Bilevel DirectClass 
120KB 0.060u 0:00.020

Does: 

identify -verbose -ping test.pdf

work as well?

identify test.pdf works, but identify -verbose -ping test.pdf 
will segfault

Looks like an ImageMagick bug to me
 [2010-10-03 08:20 UTC] pahan at hubbitus dot info 
What is more interesting:
identify -verbose -ping test.pdf
coredumped, but
identify -ping -verbose test.pdf
works well.

In any case, I agree it looks like ImageMagick problem. 
Sorry. I'll contact its upstream developers.

No worries. Better safe than sorry
