Game keeps crashing after /scoreboard players set #global pause 1

After I changed the scoreboard value of a fake player named #global it crashes after you move the mouse to look into a different direction.

What I tried so far:
Clearing the stat folder did not help.
Clearing the playerdata folder did not help.
Clearing all map.dat files did not help.
Clearing the scoreboard.dat did not help.

The "report to mojang" button does not seem to work for me:
