Thanks very much for the link and info. I’ve asked my host to upgrade to 6.8.1-0 specifically. They did, and unfortunately I still get an HTTP error when uploading jpgs. As you experienced, I am able to upload pngs, and they work fine.
I’m having the same basic problem. WordPress 3.3.1. Firefox 10/Mac.
After firing the POST, it GETs wp-admin/load-scripts.php, and seemingly tries to get all of the scripts associated with this plugin again. I can send a screenshot from Firebug if that’s helpful.
In Firebug, here’s the content of the POST:
