Cannot start VM in Mac OS X 10.8.2 => Fixed in SVN

|Host type:||Mac OS X|
I have already upgraded to Vbox 4.2 and it was working fine. I then upgraded to OS X 10.8.2 today, and when booting any VM, I get the following error:
VT-x is being used by another hypervisor. (VERR_VMX_IN_VMX_ROOT_MODE). VirtualBox can't operate in VMX root mode. Please close all other virtualization programs. (VERR_VMX_IN_VMX_ROOT_MODE).
Apparently this was an issue already present in the 10.8.2 beta, but it was not fixed on Apple's side.
