Thanks for reporting. Did you try 2.9.14? I know that I have fixed that python2.7 issue so in principle it should be in that release.
(if not I can find the patch which should be ready for the next release).

Cheers and thanks for the time of reporting the issue,


PS: Sorry, but I have to add the disclaimer that we technically do not support python2.7 anymore.
Which means that we do not validate that our code is running with that version of python.

Can you help with this problem?
