New submission from Gabriel Genellina <gagsl-...@yahoo.com.ar>:
On Windows, IDLE closes all open windows and exits completely, without any
error message, when selecting the "Print window" menu command.
Starting IDLE from inside a console, one can see the error message:
Exception in Tkinter callback
Traceback (most recent call last):
File "D:\apps\python32\lib\tkinter\__init__.py", line 1399, in __call__
return self.func(*args)

command = idleConf.GetOption('main','General','print-command-win')

"found: %r" % (rest,))
configparser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found
: '%s'
It is trying to read this entry from the config-main.def file:
[General]
print-command-posix=lpr %s
print-command-win=start /min notepad /p %s
For a ConfigParser file, those %s should be %%s instead. Previous IDLE versions
(2.7 and 3.1) read the same entry without problem; I suspect they were using a
RawConfigParser or processing the entry in a different way.
As a workaround, replacing %s with %%s in config-main.def is enough, until the
code gets fixed.
