Package: ipython3 Version: 5.1.0-3 Severity: normal Dear Maintainer,
I was trying to understand a module and when I hit a ? ipython3 exited with the traceback below. I looked at https://github.com/ipython/ipython/issues/10381 And have a quick reproducer. import numpy x = numpy.z<TAB> (Autocomplete to zero, add ?, hit enter) x = numpy.zero? (read help) Crash My traceback ------------ In [41]: e[0].get_properties? Object `get_properties` not found. In [42]: e[0].get_properties?
