if the debugger says it's NULL, it must be so, perhaps some overlooks? This is 
the first time I ever got this crash.
 
What I did is very simple, create a new vm (XP Mode vm this case, shouldn't 
matter), boot it, take a snapshot, boot vm again, then immediately power if 
off, now try to restore the snapshot, and got that error.
 
I am trying to recompile the latest svn code right now to double check this

Do you have a reproduction scenario? Without one it's nearly impossible to find 
this bug. The call trace below provides no information which would give hints 
what could lead to this. We don't fix bugs by inserting a check based on the 
fact that the pointer was NULL. The cause needs to be investigated, as the 
pointer must not be NULL by design in this place.
