Assertion error in VMMDevHGCM.cpp

[user-jon]

Host PC: Ubuntu Gutsy 7.10, Virtualbox 1.5.6
Guest: Ubuntu Feisty 7.04, Virtualbox Guest Additions 1.5.6

VirtualBox works well for me most of the time, so this is not easily reproducible.

• First thing I noticed was that the VM had mostly hung.. (ie.I could see the display via VRDP, but it was completely unresponsive, it did respond to pings, but connections via ssh or http were immediately accepted then disconnected so I couldn't log on).
  
• So I did a, VBoxManage 'savestate', which completed very quickly (I was a bit surprised how fast that was).
  
• Then when I restarted the VM, I encountered the error message below:

  user@zeus:~$ VBoxVRDP -startvm Feisty
