Ah, I didn't appreciate there were rdeps which would need to be updated
for this too.

I've been working on a script to assist updating code to work with
wxPython3, which might be helpful here if the python code in grass has
changed a lot between 6.4.x and 7.0.0 such that backporting the changes
is difficult:

I tried it on the 6.4.3 package, and with a bit of manual tweaking
the startup wizard works, but the GUI after that doesn't.  I'll send
the debdiff of that in case it's useful.
