btrfs crash

When I was unsuspending my notebook today btrfs suddenly crashed the kernel. Unfortunately the only debug output I have are some pictures made with a shitty mobile phone camera. Maybe they're of some value for you anyway: http://image.bayimg.com/eaodgaadc.jpg (1.3M, 5000x2500px)

I'm using Arch Linux, kernel 3.3.2, btrfs 0.19.
