My kids found this same bug this morning. Both using an ipod touch 4th gen, both updated to MCPE 0.6. When the visiting player in a wi-fi game touches one of the host's chests, the game crashes, exits. Host can use chests with no problem. "Closing" Minecraft from the task switcher and restarting has no effect, chest touching crash still occurs.
This is on an "exiting" world from 0.5, have not yet tried on a new world generated in 0.6.
