I just installed 3.5 RC1 freshly to play around with it. Install went smooth but when I try to upload an image I get:
Fatal error: Class 'Imagick' not found in /var/www/web15/html/BETA/wp-includes/class-wp-image-editor-imagick.php on line 63
The image however is uploaded and I do see it within the media library. I thought that WP3.5 was supposed to only use imagick if its actually on the server and simply not use it when it is not present?!
