New submission from Giovanni Lombardo <g.lomba...@protonmail.com>:
The issue arises by simply calling configure on the Scale widget of the themed
tk (ttk) widgets set:
```
cursor = scale.configure('cursor')[-1]
```
The above casues the following error:
```
File "C:\Users\Giovanni\Tests\test_scale.py", line 604, in main
cursor = scale.configure('cursor')[-1]
File
"C:\Users\Giovanni\AppData\Local\Programs\Python\Python37\lib\tkinter\ttk.py",
line 1090, in configure
kw.update(cnf)
ValueError: dictionary update sequence element #0 has length 1; 2 is required
```
The interpreter is:
```
Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit
(AMD64)] on win32```
