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.

This is now fixed in IOBinding.py 1.21 and 1.19.8.2, NEWS

1.831.4.29.

>> except (ImportError, locale.Error):



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....
