PATCH: hobbitlaunch segfaults on empty task list

["Cleaver, Japheth" <jcleaver (at) soe.sony.com>]

When hobbitlaunch is started with an empty list of tasks to run (or an
empty file, period), it segfaults. This patch resolves AFAICT, letting
hobbitlaunch sleep and try again at its regular interval. Seems to work
OK on my systems.
