We loaded a new world to replicate the error. This was a fresh game, and after I crafted an item, his game would crash. My game would be fine.
after some testing, we have determined the following
Linux host, Linux Craft: undetermined
Linux host, Windows Craft: Linux Crashed to desktop
Windows host, Linux Craft: Linux Crashes to desktop
Windows host, Windows Craft: Linux Crashes to desktop
Crash Log
IMPORTANT: Further testing proved to show that the game crashed after crafting even in a single player game.
