trading with a villiger bug

So, wheres the crashlog? Mojang cant do anything without more information and/or the crashlog!

Was there an iron golem close? It was likely that was the crash.

Probably duplicate of MC-1608

Please provide a crash report.

same here. I created a villager shop with MC Edit but no other Mods or changes made to Minecraft or the map.
When I try to buy a map (in the past maps were blank and contained no data, I wanted to test if this was already fixed) the game shows just a blank dirt-screen and nothing more happens until I close the MC Window.
