WordPress: An error occurred in the upload

After updating to WordPress 3.5, I started getting the following error when uploading files using the Add Media button as a non-admin user:

Error: An error occurred in the upload. Please try again later.

The image seems to finish uploading, but right at the end this error message appears.

This doesn’t happen for the administrator, only the other roles. I’ve even tried giving the other role full admin capabilities, but the error still appears.

Is this a bug? Or am I missing something?
