This bug used to be transient for myself, however it now crashes my VirtualBox (4.0.12-72916~Ubuntu~natty) when switching to full screen periodically, which is a showstopper, literally for Powerpoint presentations. From the logs, it appears the VBox instance dies just prior to seeing this message. This is in addition to when I suspend my HP dv7z laptop.
