*What I expected to happen was a Villager to appear to sell me the custom item for 10 diamonds
*What actually happened was the game client crashed and now that area causes the game client to crash permanently everytime for everyone who comes into that area.
Describe what happened here
I enterd this code and it crashed soon as i hit the button to summon...
/summon Villager ~ ~1 ~ {Offers:{Recipes:[{maxUses:1,buy:{id:264,Count:10},sell:{id:261,Count:1,Damage:1,tag:{ench:[{id:34,lvl:4},{id:48,lvl:4},{id:49,lvl:4},{id:50,lvl:4},{id:51,lvl:4}],display:{Name:Andúril}}}},{maxUses:2,buy:{id:264,Count:10},sell:{id:261,tag:{ench:[{id:34,lvl:3},{id:48,lvl:4},{id:49,lvl:4},{id:50,lvl:4},{id:51,lvl:4}],display:{Name:Bowey}}}}]}}

But i have had this also crash in the same way when not using a Villager, but instead a Custom Spawner which leaves that particular chunk un-usable to anyone, crash report for that is @ http://pastebin.com/54gZxkiQ

Duplicate of MC-27442
I find the duplicates and crash reports here funny - the ticket itself has nothing to do with Block 36 or Horses, each of which are key requirements to cause their respective crashes.
I followed OP's steps, and I'm unable to reproduce. I get a villager which offers two custom bows. No crashes even when examining the trades, buying and using the items, or reloading the chunks. Just posting this as a heads-up in case anyone else comes here, sees that harmless command, and gets worried that summoning custom villagers has been broken (when it hasn't), like I did.
