Macbook Pro crashes when I remove power while hibernated
I ran into a similar issue with my own late 2013 Macbook Pro running 10.9.3. In the end, I had to run the following commands with root privileges:

pmset -a darkwakes 0
pmset -a standby 0
pmset -a standbydelay 0
pmset -a lidwake 0
pmset -a acwake 0
pmset -a destroyfvkeyonstandby 1 hibernatemode 25


Once I did that, I found that I needed to wake the laptop by touching the power button (pmset -a lidwake 0 disables the automatic wake-up when you open the lid) but my MacBook Pro now hibernates properly and does not crash.

I have a post on the issues I had with 10.9.2 available here:
