Stuck, could not move character

I opened a Tribal Chest and somehow became unable to move. It wasn't the weapon swap bug because I have no second weapon equipped.

I got a screenshot with /debug if it's any help. I was wondering if I might have gotten stuck between a chest and a rock. You can see a town portal up, which unfortunately I couldn't use. Changing left-click to a wand blast made no difference. I had to alt-F4 and restart.
