I think I went through two MBPr 15" machines before I got one that didn't have the problem. I still think it's possible some software I had was triggering it initially, but once it happened a few times, even a clean install with nothing on it could trigger it. Was very frustrating.
I wonder if the most recent VMWare version would help.
"I managed to fix this by going to the Virtual Machine Settings, clicking Advanced, and then checking the "Pass power status to VM" checkbox."
Haven't tested extensively, but I haven't had a crash in the past day.
Stop presuming, get facts. OSX Mavericks is known for its crashing problems.

The only issue I have is with the trackpad going out from time to time but a quick reboot fixes the problem.
