I rebooted the guest and tried again after uninstalling/reinstalling the guest additions but that didn't help.
Aside from reverting to 3.2.29, found only these 2 workarounds:
-remove the guest additions, X starts working again (issue re-occurs if I reinstall the additions)
-upgrade to 3.8.13, this apparently resolves everything with no issues so far, guest + X + additions working smoothly.
I upgraded to the 3rd kernel build and the problem remains.
Problem seems to be fixed with the latest Virtualbox 4.2.14 (released today).
