When in creative with cheats enabled (though possible in survival etc. as well), the /spawnpoint command seems to be working incorrectly. when i die or use the /kill command after having set my spawnpoint using /spawnpoint, i respawn in the wrong location and a message appears in the chat saying
"your home bed was missing or obstructed."

to reproduce this bug:
1. create a world with cheats enebled
2. go somewhere and type /spawnpoint
3. go somewhere else and die
4. take note of the chat after respawning.
