This is not a problem with repr; it is a bug with str.

I certainly support a flag for repr meaning "This was really str; repr
got called because the container doesn't have str, but go back to str
for the contents."  (Alternatively, write an explicit repr that does
that, add it to the builtin types, and make it available for easy use
with extensions.)

I'm not sure I fully understand this problem, but I would expect the
right solution to be a change to either Exception.__str__ or the way
filename-related exceptions are initialized.  Changing all of repr is
again overkill.
