VM crashes when accessed by VNC

[hgoshev]

I am running the latest VirtualBox with the Extension Pack installed. I am running a Mac OS X Server as the guest and have configured Screen Sharing through the system preferences. Each time I try to access the VM remotely via VNC, it crashes almost immediately with the following message: "A critical error has occurred while running the virtual machine and the machine execution has been stopped". This has happened with a different Mac OS X version as well, and occurs regardless of what type of VNC client I use. I tried modifying the VM's parameters like CPU count, RAM size, video memory, 2D/3D acceleration and so on, but nothing has helped.

Please attach the VBox.log file of such a VM session.
