Ouch ! It's very difficult to say if it's related or not. But at the 
first glance, I would say it is not related to the containers as it's 
the "apparmor_parser" process which caused this kernel BUG.
In any case, it is probable your kernel is not in a consistent state.

IMO you should consider sending this BUG to kernel-team at lists.ubuntu.com 
(assuming it occurred on lucid).

Thanks
