Update:
The crash only happens if you set the sidedisplay to display health. After quitting the game, a blank player will appear and then trying to bring up that player's name using tab will cause a crash.
Sooo.... scoreboard creating ghosts that then cause the crash?

Unable to reproduce in 13w21b.

Reproduced in 13w21b
do the following.
/scoreboard objectives add Health health
/scoreboard objectives setdisplay sidebar

Log out then, log back into the world.
Then,
/scoreboard players reset [tab]
game crashes.
It tries to access a name that is invalid, the game creates a "ghost" when you log out. You will see an empty slot with a 20 for health in the sidebar.

Ah I was doing it wrong. I entered the reset command first then hit tab, but confirmed now 🙂

This is spit out when hitting esc in a ghosted world.
