That should fail; it would equally fail if you tried
    myCat = pywikibot.Category(mySite, "Garbage")
since "Garbage" is not in the Category namespace.  In other words, the fact 
that the category title starts with "Wikipedia:" has nothing to do with it. 
However, this should work:
    myCat = pywikibot.Category(mySite, "Kategori:Wikipedia:Globalt 
perspektiv-samtliga");

That one does seem like a bug.  The namespace number ought to match the 
actual title.  I'll investigate further.
