The temporary solution is to make an empty file called config/crontabber.ini which I shouldn't have to :)

@twobraids is this solved by 0ec1864 ?

I've found another case where this happens.

I upgraded to the latest and greatest configman into socorro (as part of replacing socorro.cron.crontabber with crontabber) and I ran this:

PYTHONPATH=. socorro/cron/crontabber_app.py --admin.conf=sluggish/crontabber.ini.new

and got this

Traceback (most recent call last):
  File "socorro/cron/crontabber_app.py", line 64, in <module>
    sys.exit(main(CronTabberWrapper))
  File "/Users/peterbe/virtualenvs/socorro/src/crontabber/crontabber/generic_app.py", line 211, in main

    raise NoHandlerForType(type(a_source))
configman.value_sources.source_exceptions.NoHandlerForType: <type 'str'>

The solution in this case was simple, I did mv sluggish/crontabber.ini.new sluggish/crontabber.ini.
It's fair that configman doesn't know what the heck to do with a filed called something.something.new. That was my mistake. The mistake configman did was swallow the error and spit out a different one.
