problem with ImageMagick @6.8.9-6_0+x11

[Bill Christensen]

Hi All,

The most recent version of ImageMagick (6.8.9-6_0+x11) fails to process 
WordPress image uploads properly. I have not tested with any other systems.

Setup: Mac 10.9.4, Apache 2.2.27, PHP 5.5.15 MySQL 5.5.38 PHP Shortcode 
(<?)is OFF.
Also occurs on a system with Mac 10.7.5, Apache 2.2.27, PHP 5.3.28, 
MySQL 5.1.72 with PHP Shortcode ON.

Expected behavior: When an image is uploaded via WordPress, ImageMagick 
is called to create one or more pre-defined smaller versions, for 
example a 150x150 px thumbnail. All images are then visible and 
available via the 'Media Library' in WordPress admin, so they can be 
included in various posts.

Actual behavior: The original and smaller versions appear to be created 
correctly as verified by direct inspection in the uploads repository on 
the server. The Media Library displays the image name but does not 
display the image itself and any attempts to insert the image into a 
post will go through the proper steps but the image does not display.

Workaround: Reverting to ImageMagick @6.8.9-1_0+x11 allows images to 
upload properly.

I have also reported this on WordPress 
<http://wordpress.org/support/topic/imagemagick-689-6_0x11-fails-to-process-wordpress-images-properly?replies=1#post-5921323> 
and have submitted a MacPorts ticket 
<https://trac.macports.org/ticket/44728>, but other software which uses 
ImageMagick may be experiencing similar problems.
