print function imported from __future__ causes inspection to fail

[Daniel Lee]

e.g.
'''
test.py
'''
from __future__ import print_function

class Class(object):
    def method(self):
        print('foo', end=' ')

WARNING: Inspection of module path\test.py failed.

This may be related: If you have a from future print import and you run pythoscope --init, the resulting pickle files crash pythoscope on load when you try to run pythoscope again.

To reproduce, put a python file with the from future bug and one that analyzes fine in the same directory.

run pythoscope --init

pythoscope will complain with a warning:
WARNING: Inspection of module <bad_module_here> failed.

Then run pythoscope good_module.py

I get the following traceback:

ERROR: Oops, it seems that an internal Pythoscope error occurred. Please file a bug report at https://bugs.launchpad.net/pythoscope
