Crashing on start up after dying in a Nether portal

Now when I go to enter the world it crashes.

*What I expected to happen was...:
The world to regenerate when I should respawn after dying.

What actually happened was...:
I died in the portal and now I don't regenerate at all.

Steps to Reproduce:
1. Be on fire in the Nether
2. Attempt to enter the portal
3. Die while wait for the portal to transport.
