Crash when mounting horses, getting in boats or minecarts

Duplicate of MC-14126.

It's not a duplicate. It's happening with minecarts and boats, not just horses.

Clearly same crash.

Better question is: what key is your "right-click" binded to?

Did the other ticket report it happening with minecarts and boats? If not, then it's not a dupe.

My use key is bound to the right arrow key on my keyboard, it's never been a problem before the 1.6 snapshots. I tried binding it to other keys, and it still crashes.

Added Boats and Minecarts to MC-14126.

Regarding the keys: No matter what I bind the use key to it never crashes.

This issue has not been resolved for me in 13w19a.

I figured out the problem!

The game crashes when mounting a horse/boat/minecart with the "use" key, but the problem is actually with the "sneak" key. I have my "sneak" key bound to mouse button 2, and I'm guessing the crash is happening because it doesn't know how to display a mouse button in the "press <key> to dismount" text.

I changed my "sneak" key to a keyboard key, and it works.

Finally a way to reproduce it, confirmed! Thanks for the info, updating summary and description of MC-14126.
