Comment (by dd32):

 After digging through this, and seeing that indeed the methods used here
 such as `exif_read_data()` and `getimagesize()` don't appear to internally
 use Imagemagick when available (As I initially assumed from the logs),
 I'm pretty sure this is a PHPUnit bug, or an issue with PHP Itself.

 The actual exception thrown by the phpunit handler is
 `getimagesize(http://localhost/foo-cropped.png): failed to open stream:
 HTTP request failed! HTTP/1.1 404 Not Found`,  which is then reported
 incorrectly. The prefix to the log message on the CLI is the Exception
 classname.
 {{{
 1) Tests_Image_Header::test_create_attachment_object
 ImagickException: getimagesize(http://localhost/foo-cropped.png): failed
 to open stream: HTTP request failed! HTTP/1.1 404 Not Found
 }}}

 Potentially related is the fact that I keep triggering segmentation faults
 and OOM errors in PHP whenever I try to diagnose what's happening.
