VirtualBox 4.0.4 console error when attempting to start any guest VM

[shlegm]

I am running a MacBook Pro with 8GB RAM and Snow Leopard 10.6.6. I just upgraded to VirtualBox 4.0.4. I can launch the VirtualBox GUI. All appears fine. I can create new VMs; edit existing VM settings. However, when I attempt to launch ANY guest (tried Windows-7, Ubuntu and even a VM of Haiku [BeOS]), I receive the console errors in the attached VBox.log.

My WAG right now is that there's a file permissions issue when 4.0.4 is installed (hence the "World writable: '/Applications'" line in VBox.log). However, before trying post-implementation permission surgery, I figured I'd throw it out to this group to see if anyone else is experiencing this and if there's a solution or a patch forthcoming

I have been able to repeat this when I upgraded 4.0.4 on a completely separate host (another MacBook Pro; 8GB RAM; 10.6.6) and had the same exact error appear.

Also, attempting to "rollback" to 4.0.2 gives me the same error. I have not tried rolling back to 4.0. If there is any other info needed, please let me know.

The directory '/Applications' has wrong permissions. VirtualBox detected that this directory is writable for non-root users. Fix the permissions of this folder and VMs should start again. This check is a security measure. If that directory is writable for non-root users, a malicious user could change some components of VirtualBox. As the VirtualBox application has special privileges, a malicious user could exploit these privileges.
