Just came across this bug, the problem I encounted was: linux-image-2.6.32-trunk-686 installed linux-image-2.6.32-5-686 installed for some reason the trunk kernel was in position 0 in menu.conf, removing linux-image-2.6.32-trunk-686 fixed the problem. If you update your default to boot linux-image-2.6.32-5-686 in menu.conf should also fix the problem.
