Pretty much. :-)

I'm not using ConfigObj myself these days, so development has stalled. The *best* place to report an issue is on the bug tracker, so that it doesn't get lost:

So parsing into lists is done by ConfigObj before a value is sent for validating.

The "right" thing to do is to escape the comma with quotes:

	 foo = "bar, bar"

Having said that, if your spec specifies a string then a list should *fail validation*. You could write a custom validator yourself that will force non-list values.

All the best,
