I'm having the same problem in 5.3.1

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

While using PHP 5.3.7 with Imagick 2.3.0, I still have this issue.

Ok, this was fixed in Imagick 3.0.0 RC1, sorry for bothering

Same problem persists on Windows-7, Xampp php 5.4.4, Imagick 3.1.0RC2, ImageMagick 6.6.5-9 2010-11-15 Q16 http://www.imagemagick.org

It does work, when using new Imagick('filenamehere') where filenamehere is not a url.

Anyone know what prevents it from being able to readImageFile of  fopen of a url? Or a file for that matter.
