TASK DESCRIPTION Recently the welcome script failed on Travis: https://travis-ci.org/wikimedia/pywikibot-core/jobs/58246884#L756 As that output is a bit unwieldy here is the output easier to read:

[MSG ] ***Log page is not exist, getting information for page creation Traceback (most recent call last): File "/home/travis/build/wikimedia/pywikibot-core/pwb.py", line 215, in <module> run_python_file(filename, argv, argvu, file_package) File "/home/travis/build/wikimedia/pywikibot-core/pwb.py", line 84, in run_python_file main_mod.__dict__) File "./scripts/welcome.py", line 1017, in <module> main() File "./scripts/welcome.py", line 998, in main bot.run() File "./scripts/welcome.py", line 831, in run if self.makelogpage(self.welcomed_users): File "./scripts/welcome.py", line 661, in makelogpage text += u'\n!%s' % self.site.namespace(2) TypeError: unsupported operand type(s) for +=: 'NoneType' and 'unicode' CRITICAL: Waiting for 1 network thread(s) to finish. Press ctrl-c to abort ```

So text is None and looking into the code reveals that it translates it using the site's language and a fixed logpage_header table.

text = i18n.translate(self.site, logpage_header) text += u'\n!%s' % self.site.namespace(2)

And logpage_header has only the keys `_default`, `no` and `it` and without `fallback` set to `True` it won't use `_default`. Interestingly I can't find any recent changes that would've lead to this problem (e.g. `fallback` parameter removed).
