As always the big problem is that this is a significant API change for
yum, so we'd need to somehow audit every piece of code that ever used
yum and make sure this doesn't affect them negatively.
I'd guess that it probably doesn't, but it's much easier to just know
it doesn't because we didn't API break anything.

Why call exception2msg(e.value) ? Does any code actually do that?
exception2msg(e) works, right?
What is the actual problem this solves, needing to call to_utf8() in
the __str__ function, like we do in YumBaseError?
