Opening a chest crashes the game

Copied a map I was using in the stable server to 14w11b and then to 14w17a

All the content I had previously on the map work fine but when I open the chests which contains my "trees" stuff (sapplings, seeds, ...) the client crashes. Crash occurs in 11b and 17a.

Not complaining ^^ I knew the risks, but I thought you might want to know

Screenshot is extracted from a backup copy, the exact items + amounts is probably not the same, but you get the "type" of items stored in there.
