99% sure this will be a unicode thing ... as logger eats unicode instead of doing a Unicode exception.
Quickly searched the code.. Seems this is the only place where Yum sends to_unicode() to logger. Fixing this very likely fixes BZ 824663 too.

This is a bug in the subclass.
def __getattr__(self, name):
if name == 'errmsg':
# >>> implicit "return None" here <<<
The Error instance is passed to the logging module which checks if the argument is a non-empty dictionary with something like: "if e and type(e) == dict".
The first test checks for the presence of __len__ method and tries to call it, raising "NoneType is not callable" error in turn. We have to make sure __len__ is not defined by raising an AttributeError in __getattr__.
