Summary: Namespaces 828 and 829 missing
Initial Comment:
en-WP now has namespaces 828 and 829, ref: http://en.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=...
The following code throws a namespace error, but should return "Module:String":
import pywikibot;
site = pywikibot.getSite('en');
bugPage = pywikibot.Page(site, "String", ns=828);
bugPage.namespace();
828
bugPage.title();

Message:
Another way instead of forcing _getsiteinfo() would be to delete the api
chache on disk.

Message:
We introduced caching api calls at berlin hackathon because  high frequent
api calls slows down the performance of the rewrite branch enormously.
Anyway this should be solved.

That did the trick, thanks russblau!
Yes, maybe the cache should be updated whenever MediaWiki version changes? 
Just a thought.  I'll update this bug as "closed - works for me".

Message:
The rewrite branch gets its namespace info by querying the API. 
Apparently, someone (not me) inserted code to cache this information, and
you are retrieving an old, cached version of the namespaces list. 
Workaround is to insert the line:
site._getsiteinfo(force=True)
into your script, after the site=... line.  However, this really is a bug
that ought to be addressed.

Message:
Maybe I should make it apparent that I'm on the rewrite branch, and not
trunk.
I see that trunk has namespaces 828 and 829 listed in
families/wikipedia_family.py, while I fail to figure out on my own how
namespaces are mapped in the rewrite branch.

cannot reproduce that bug:
...

import pwb
import pywikibot as wp
s = wp.getSite('en')
p = wp.Page(s, 'String', ns=828)
p.namespace()
828
...
...
...
p.title()
u'Module:String'

That's just pywikibot/__init__.py, the repository itself is at revision
11085, updated as of a few minutes ago.
