Trying to suspend by closing the lid I got:

- and it didn't suspend.

It usually works, but recently I have seen it fail like this a couple of times.

(I would also expect this trace to have a structure that made it clear if it was an oops or what was going on, and some markup that abrt could use for catching it.)
