8055,VirtualBox - ERROR: Failed to save state of the virtual machine.,henry,,"Virtualbox 4.0

Host running Ubuntu 10.04
2.6.32-27-generic-pae

Guest running Windows XP SP3

I'm not sure what triggers this but it coincides with my preview window on Oracle VirtualBox VM Manager no longer reflecting what is in the VM instance. Once this happens I cannot save the state of the virtual machine.  It returns the error in the title.  Under details it has only this:

Callee RC: 
NS_ERROR_CALL_FAILED (0x800706BE)

This never used to happen when I used VirtualBox 3.x so I'm assuming its related to VBox 4.0.  Any help in resolving this would be greatly appreciated.  Let me know if I need to post logs - just tell me where they are and what file I should be looking at.
