Ok, _now_ I have run into the same problem. I have attached a small script
similar to the original entry (but shorter) which will reliably crash with
Python 3.1.4 on Windows 7 (64bit) when using a locale with a comma decimal
fraction marker (e.g., German). The stacktrace is as follows:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python31\lib\tkinter\__init__.py", line 1400, in __call__
return self.func(*args)
File "C:\Python31\lib\tkinter\__init__.py", line 2799, in set
self.tk.call((self._w, 'set') + args)
_tkinter.TclError: expected floating-point number but got "0,2"
The script runs fine with an English locale. It also runs fine with Python 3.2
on the same machine & Windows & German locale.
The reason seems to be that the Scrollbar lets its self.tk compute fractions
which self.tk returns as locale-dependent strings; the Scrollbar runs into
problems when converting these strings into floats.
