With libpython.py loaded in gdb, when backtracing and trying to pretty-print frame objects along the way, this error is sometimes raised:

Python Exception <type 'exceptions.TypeError'> object of type 'FakeRepr' has no len()

See attached patch against tip.

Thanks for the report and patch.  

The next step required for this issue is for someone to write a unit test.

How do you reproduce the issue? I'm not sure that the patch is correct.

Could you provide some more details on how to reproduce this issue? If I am able to reproduce the issue, I'll write a few unit tests and get this patch rolling again.
