> Looking at the non-interpolation of '%(asctime)s', etc again, I'm wondering that myself. Maybe this is a bug in configobj? That doesn't make sense though. I'm wondering if the keyword 'format' has something to do with it.

Changed key 'foramt' to 'formt'. No change on non-interpolation of 
'%(asctime)s'
