There is more to this bug than appears. I'm guessing that the name
mangling code in locale (e.g. the normalizing code) is locale dependent. 

See this example:

#!/usr/bin/python2.5

import locale

print 'TR', locale.normalize('tr')

print locale.setlocale(locale.LC_ALL, ('tr_TR', 'ISO8859-9'))

# first issue, not quite the same coming out, as came in
print locale.getlocale()

# and this fails
print locale.setlocale(locale.LC_ALL, ('tr_TR', 'ISO8859-9'))



First, the value returned from getlocale is ('tr_TR', 'so8859-9'), not
('tr_TR', 'ISO8859-9'), and the second setlocale fails.
