Clearly it crashes for your VM somewhere before the snapshot is actually 
completely taken, so it's very different to the (now fixed bug) we had 
in BETA3 which always crashed when the snapshot was complete. I wonder 
if you could get us a stack trace of the VM process (either by running 
it in a debugger straight away or from the core dump).

As you have 3D enabled which adds a big collection of potential 
troublemakers specific to your setup it'd help us a lot to see where it 
crashes for you. In my local tests I couldn't reproduce your problem.

Oh, and to get the terminology right: this is about taking an online 
snapshot (which the log file snippet points out already) :)

I don't know why I didn't have the idea years ago to have all machine 
state changes in the release log. They're key points in the API code 
flow, and it's good to know if some change happened or not.
