Summary: Namespace alias error with preloading and page.exists()
Initial Comment:
As of revision 11144, the following attempt to preload a page in a specific aliased namespace on Portuguese Wikipedia fails:
import pywikibot;
site = pywikibot.getSite('pt');
site.login();
from pywikibot.pagegenerators import PreloadingGenerator, PagesFromTitlesGenerator;
pageGen = PreloadingGenerator(PagesFromTitlesGenerator([u"Usuário:Vitorvicentevalente"], site=site));
for page in pageGen:
    print page.title();
Gives the following output:
Retrieving 1 pages from wikipedia:pt.
WARNING: preloadpages: Query returned unexpected title 'Usuário:Vitorvicentevalente'
Creating a Page object and asking if the page exists also fails:
import pywikibot;
site = pywikibot.getSite('pt');
site.login();
page = pywikibot.Page(site, u"Usuário:Vitorvicentevalente");
page.exists();
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pywikibot/page.py", line 417, in exists
return self.site.page_exists(self)
File "pywikibot/site.py", line 1180, in page_exists
return page._pageid > 0
