[New-bugs-announce] [issue26673] Tkinter error when opening IDLE configuration menu

[wysaard]

New submission from wysaard:

I'm using Python 3.5.1 on Arch Linux. I've restalled the python package which provides IDLE, and the tkinter package which is used by IDLE, but to no effect.

My problem is this: When in the menu at the top in IDLE, I click on Options -> Configure IDLE, the menu will stop responding, and nothing happens after that.

Doing this when I run IDLE in a terminal provides the following error on clicking `Configure IDLE`:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python3.5/tkinter/__init__.py", line 1549, in __call__
    return self.func(*args)
  File "/usr/lib/python3.5/idlelib/EditorWindow.py", line 516, in config_dialog
    configDialog.ConfigDialog(self.top,'Settings')
  File "/usr/lib/python3.5/idlelib/configDialog.py", line 74, in __init__
    self.LoadConfigs()
  File "/usr/lib/python3.5/idlelib/configDialog.py", line 1086, in LoadConfigs
    self.LoadFontCfg()
  File "/usr/lib/python3.5/idlelib/configDialog.py", line 988, in LoadFontCfg
    self.SetFontSample()
  File "/usr/lib/python3.5/idlelib/configDialog.py", line 866, in SetFontSample
    self.labelFontSample.config(font=newFont)
  File "/usr/lib/python3.5/tkinter/__init__.py", line 1330, in configure
    return self._configure('configure', cnf, kw)
  File "/usr/lib/python3.5/tkinter/__init__.py", line 1321, in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: expected integer but got ""

I have no idea what to do here.
