Why does one work, but not the other?

My usual solution to that is generically written:

dict([(k, v) for k, v in d.iteritems()])

...taking advantage of the fact the you can pass dict() a list of
tuples. Your specific example would be written:

db = dict([(k, str(v)) for k, v in self.options.iteritems()])

I use iteritems more often, since it doesn't create an intermediate
structure.
