_safe_repr() tries to handle the case where two objects are unorderable by
ordering on (str(type(key)), key, value), but this fails when
str(type(key)) is equal for two objects, but key is different and
unorderable. Easy fix: order just on the string representation.

I don't know if this is still relevent, if it is please provide a test
that demonstrates it. I've checked the code and found that the code to
be patched no longer exists. To me, it looks like it might be resolved.

It's still a problem, as the test case demonstrates.
