On some systems a font reports a zero width for the
'0'character (seen with a broken font on openSUSE).EditorWindow.set_width()divides the Text widget's pixel width by that value, so theZeroDivisionErrorprevented IDLE from starting at all.set_width()now falls back to the configured width when the measured width is zero.self.widthis consumed by the=== RESTART ===separator in the shell and by the squeezer's line wrapping.
