--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
Using a standalone reproducer:
...
$ cat test.py
class BadKey:
def __repr__(self):
return "Bad Key"
class ReallyBadKey:
def __repr__(self):
return BadKey()
a = {"result": {ReallyBadKey(): "world"}}
print (a)
...
we can see the behaviour with python3:
...
$ python3 test.py
Traceback (most recent call last):
File "test.py", line 12, in <module>
print (a)
TypeError: __repr__ returned non-string (type BadKey)
...
and python2:
...
$ python2 test.py
{'result': {Traceback (most recent call last):
File "test.py", line 12, in <module>
print (a)
TypeError: __repr__ returned non-string (type instance)
...

I don't see a pressing need to fix this on the gdb-12-branch, so I'm closing
this as resolved-wontfix.
Anybody running into this with gdb 12.x and finding it annoying can use the
patch posted in this comment.
