Summary: Unsupported 'locale' setting causes Idle to crash on startup

Initial Comment:
If the 'LANG' environment variable is set to an 
unsupported value, Idle crashes on startup.

The error occurs in IOBinding.py, as follows:

Traceback (most recent call last):
  File "Resources/__argvemulator_idle", line 4, in ?
    execfile(os.path.join(os.path.split(__file__)[0], 
"idle"))
  File "Resources/idle", line 4, in ?
    import idlelib.PyShell
  File "/Applications/MacPython-2.3/IDLE.app/
Contents/Resources/idlelib/PyShell.py", line 22, in ?
    from EditorWindow import EditorWindow, 
fixwordbreaks
  File "/Applications/MacPython-2.3/IDLE.app/
Contents/Resources/idlelib/EditorWindow.py", line 39, 
in ?
    class EditorWindow:
  File "/Applications/MacPython-2.3/IDLE.app/
Contents/Resources/idlelib/EditorWindow.py", line 43, 
in EditorWindow
    from IOBinding import IOBinding
  File "/Applications/MacPython-2.3/IDLE.app/
Contents/Resources/idlelib/IOBinding.py", line 31, in ?
    locale.setlocale(locale.LC_CTYPE, "")
  File "/Library/Frameworks/Python.framework/
Versions/2.3/lib/python2.3/locale.py", line 381, in 
setlocale
    return _setlocale(category, locale)
locale.Error: locale setting not supported


Here are the offending lines in IOBinding.py:

try:
    import locale
    locale.setlocale(locale.LC_CTYPE, "")
except ImportError:
    pass

As it's not an 'ImportError'...

The error is reproducible on Mac OS X 10.2.6, running  
MacPython-2.3.  I have not been able to test on other   
operating systems.

I've tested the change on my system, and it looks good.  
No crashing on startup, and everything else seems to 
function as it should.

I suppose the right thing to do here is

except (ImportError, locale.Error):

Is that correct?
I'm going to be away for a few days....
