Bug with 3.4? WPMU DEV Dashboard Plugin Problem

When my WPMU DEV Dashboard plugin is activated, every time I publish, save draft, or update a page or post the screen goes completely blank. The process actually occurs in the backend. I know this because when I navigate my way back it shows completion (of whatever... such as post is now published). When I deactivate the WPMU DEV Dashboard plugin, this problem no longer occurs.

Is this a known bug?
