Re: Cube-info dictionary type error on linux cli using Python 3.9.2

[Jim Segrave]

I need to look at this in depth- on my host the default python is 2.75 
(even thouogh nowadays I almost always use python3) and it does what it 
used to.

I really don't remember how the Python integration works, athough I once 
used it quite heavily to build databases of matches. I'm sure it's solvable
