Sometimes pages in namespaces with strange aliases will not be found (wikiHow)

[GoogleCodeExporter]

I'm downloading the English wikiHow and the script finds 0 revisions for every 
main space talk. 
For instance: http://www.wikihow.com/Discussion:Make-a-Robot-at-Home «The page 
"Discussion:Make a Robot at Home" was missing in the wiki (probably deleted)».
This is probably because they changed the name of the namespace in some weird 
way, so they always use Discussion: instead of Talk: (although the latter 
redirects to the former: http://www.wikihow.com/Talk:Make-a-Robot-at-Home ) and 
for some reason this won't work with API, although 
http://www.wikihow.com/index.php?title=Special:Export gives you the required 
pages.
wikiHow is known to patch/hack MediaWiki in a lot of improper ways, but I don't 
understand what could cause this problem.

Actually I've looked at the xml and there are several talks, so it doesn't 
depend on the namespace. Perhaps the error is misleading, it could even be a 
temporary problem.

Strike that, it doesn't happen with talks only, but with all titles containing 
a space. Perhaps because wikiHow uses dash instead of underscore to replace 
space in URLs?

I tried to archive WikiHow in the past (Spanish one) and I saw some weird 
behavior. Further research is required on this.
