Crash on "Updating screen events"

Crashed on closing of inventory. It was the nexus in dvz (a modified server that uses vanilla client), which is the equivalent to a large chest. I think that I was pressing 1 and e when I closed it, but im not sure.

EDIT: reproduced in single player. Seems to ocour when you swap and exit the inventory on the same tick. See crash-2013-02-28_21.16.25-client
