Very puzzling. The only obviously even possibly relevant change from 3.4
to 3.6 is that the Tk version for 3.4.3 is 8.6.1. configDialog is
identical in 3.4 and 3.6.
tkinter is a bit stupid, as it does not report the command that was
passed to Tcl. It would be helpful if you printed it out before the
call, i.e.
print(_flatten((self._w, cmd)) + self._options(cnf))
Can you inject this into both versions of the code?
There is something about fonts. It could also have something to do with
Xft, a compile-time option of Tk, to use fontconfig (vague guess).
I decided to open a tracker issue so this does not get lost.

Here is a small patch which improves the error message a lot:

Instead of just the error, this prints the full Tcl stack trace.

Is there a chance to get this fixed upstream in Tkinter?
