Your logic is correct - but missing one step.
The default values are filled in by the validation process (as is the
type conversion to integers).
>>> from configobj import ConfigObj
>>> from validate import Validator
>>> c = ConfigObj( 'test.conf', configspec='test.spec' )
>>> c
{'key1': '5'}
>>> c.configspec
{'key2': 'integer(default=15)', 'key1': 'integer(0, 30, default=15)'}
>>> v = Validator()
>>> test = c.validate(v)
>>> if test != True:
... print 'Something went wrong ;-)'
>>> c['key2']
15
Untested, but should work. ;-)
Let me know if it doesn't.

I changed a lot in the implementation of unicode from 4.2.0 beta 2 to
the released version, as well as other tinkerings. (See the homepage
http://www.voidspace.org.uk/python/configobj.html for a download link).
I would highly recommend using the latest version.
All the best,
