Python3.12: two tests fail

[penguinpee]

I just applied c00b217 for making the package Python3.12 compatible in Fedora.

Now I have two tests failing with TypeError: 'float' object cannot be interpreted as an integer:

I believe this is related to Python3.12 changes, but it's beyond me to investigate further, atm.
