    Yeah, I wasn't sure who was responsible for this module. Wasn't clear
    from the log.

    Right. Looking at the code, pre .35-rc2 loads the dynamic debug code after
    verifying that the module is loadable. So it's a bit harder to hit
    it, although it can still fail at the following module_finalize() or at
    the parse_args(), so the problem is there.
