so far I tested grass 6 and 7 with wxpython 2.9 only. I am not sure what's
the difference between 2.9 and 3 but I hope it's not so big.

GRASS 6.4.3 was not yet working with newer wxPython, that's why you get the
error. Current GRASS 6.4 branch should somehow work although I was not able
to test the whole wxGUI, so you can expect some glitches. I would
appreciate if you can test and report errors which can be related to new
wxPython.

Nothing critical, I didn't remove it yet because I'm not sure if it's
needed with wxPython 2.8.

I think it doesn't really break anything (right?) and it's hard to track
what's the problem so I usually ignore it.

Thanks for reporting,
