[issue45957] _tkinter.TclError: expected boolean value but got ""

Thank you Ali. It confirms my guess, but it is still not clear why we get a Tcl_Obj rather of None or empty string.

Please examine what is the output of the following code:

res = root.tk.call('wm', 'overrideredirect', root._w, True)
print([res.typename])
print([res.string])

If the first print crashes comment out it.
