crashing cpsconf.py: Flask_OpenID-1.2.2 has a bug(?) that was not present in 1.2.1

When installing director on a clean platform, cpsconf.py crashes, reporting the following trace.

Traceback (most recent call last):
  File "/usr/local/bin/cpsconf.py", line 5, in

I never saw this before, but I noticed that in my previous development for OpenID, I installed Flask_OpenID-1.2.1 and here, through dependencies Flask_OpenID-1.2.2 is installed. So I replaced 1.2.2 by 1.2.1

pip uninstall flask-openid
pip install https://pypi.python.org/packages/source/F/Flask-OpenID/Flask-OpenID-1.2.1.tar.gz

and re-installed the director. Now cpsconf.py neatly ran to completion.

I still have to check if the results are OK. I will also issue a bug report to the package developer(s).

I'll get back on this by tomorrow.

I checked on all three systems where I recently deployed ConPaaS, all have Flask_OpenID version 1.2.1 installed by default.

The bug was fixed in https://github.com/mitsuhiko/flask-openid/issues/38 cpsconf.py now runs fine with Flask_OpenID version 1.2.3 Closing the issue
