VirtualBox: The Updated Problem

There was a problem with Monday's updates for Virtualbox on Linux Mint.
Once installed, they blew things up rather violently, depending on your setup, you could either end up with a box that couldn't login (via the graphical login manager) or (my case) with a box that wasn't able to run programs.
Right after installing this update on the MacBook Pro programs (some of them, not every single one) refused to load, and those that didn't they didn't even produce an error message, really annoying, right?

In the end, the fix for the update shenanigans was pretty easy to do, but the really cool thing is that Linux Mint released a fix for this update right the same day.
