OK. I need to convince you guys (any myself) first that there is a
problem though. Here is the patch for a proof of concept... I think my
previous description of the POC may have been ambiguous, as the change
could have been implemted in more than one place in FlexCompleter.py.
Having applied this to FlexCompleter.py (or even rlcompleter.py at the
right place with a vanilla python shell), things like sys.<tab> fail on
my system (dont have access to a proper linux system to test.) Please
apply and verify.
My diagnosis is that the error lies in pyreadline at
the line "if r and r not in completions:", since this will break as soon
as a duplicate entry is detected. But before we discuss this further,
please verify that my POC is not due to a wacky configuration on my side.
Proof of concept for duplicate entry failure. After applying, do in
IPython: import sys; sys.<tab>
