Public bug reported:
gnome-language-selector crashes if LANG is not set in either
/etc/default/locale or /etc/environment.
The error message is:
line 59, in getMissingLangPacks
if "_" in default_lang:
TypeError: argument of type 'NoneType' is not iterable
where lines 57-60 of /usr/lib/python2.6/dist-
packages/LanguageSelector/LanguageSelector.py read:
57: # now check for a missing default language support
58: default_lang = self.getSystemDefaultLanguage()
59: if "_" in default_lang:
60: default_lang = default_lang.split("_")[0]
and getSystemDefaultLanguage reads:
def getSystemDefaultLanguage(self):
conffiles = ["/etc/default/locale", "/etc/environment"]
for fname in conffiles:
if os.path.exists(fname):
for line in open(fname):
match = re.match(r'LANG="(.*)"$',line)
if match:
if "." in match.group(1):
return match.group(1).split(".")[0]
else:
return match.group(1)
return None
Because of the way this function is used, it MAY NOT return None. It
should instead return a graceful default: presumably, it should return
what is currently returned by the command 'locale' if it is not the C
locale, or some graceful default value like en_US.UTF-8.
