Full stack trace (all threads) from the log for posterity
This is just OOM, right?
If the nsTArray at the top of the stack is infallible then I would expect a more explicit
OOM crash, i.e. mozalloc_abort et al, at the top of the stack.

Frame #2 is around here:
http://hg.mozilla.org/mozilla-central/annotate/3366c0fcf9c2/xpcom/glue/DeadlockDetector.h#l276

"Crash address: 0x7" seems like a null-pointer access?

FWIW, note that thread 33 is also inside DeadlockDetector, blocked waiting for the lock.

Next time this occurs we should look for assertions in the log.

OTOH, since it hasn't occurred in 3 months we could just write it off as a random
Panda-board HW failure because this hardware is not very robust it seems.
