[Catalyst] Suddenly Failing with Moose and MOP Errors

Don't know about this specific problem, but we just ran into something
similar -- no upgrades, no changes, but Catalyst suddenly stopped loading
(DBIx::Class::Schema::connection(): No arguments to load_classes). Wound up
having to cpanm a bunch of upgrades by hand before it started working again.

So apparently our system either is configured for occasional cron-based
upgrades and we managed to wind up in an unstable state as a result (still
looking into this)... or black hats were involved.

You might be in a similar situation. :(
