Here, we wanted to ignore the error if both the field type and value are
base strings (unicode or string types). However, we are incorrectly
using isinstance() to check the base class of fldType. Change that to:
elif issubclass(fldType, basestring) and isinstance(val, basestring)
and test, and then commit!
