Then I read that this was a bug in python (issue 14252) that had been fixed, but I don't think this is the same error. That one specifically refers to subprocess.py and I don't have that in my traceback.  I have v3.4.2. On top of everything else, despite requesting a new password, all I get from the big tracker is 'invalid login'.

The above clearly shows "Successfully installed psycopg2" and that it's 
a permission error on cleanup that's gone wrong, so what is there to 
report on the bug tracker?
