Ah I see, you may still have the Ubuntu pkg for them installed though, which may be an old version which actually starts to try and do stuff now that there is a vboxguest driver in mainline too, but that old version does not support the new, stable API as merged into the mainline.
So if you don't care about the add-ons instead of upgrading yopu can also remove the Ubuntu pkg for them.
