Public bug reported: I noticed the following messages in VBox.log while trying to figure out why virtualbox occasionally segfaults while shutting down an Ubuntu 11.10 guest. I'm not sure whether this is related to the segfaults or a different issue. The message implies I should report it, so here it is.
