I've done some debugging and this is what I've found so far:

1) the key error 104 is thrown because _namespaces[104] does not exist as a dict entry in site.py code (I enjoy the humor of the error message number and the index to the _namespaces dict being the same number!)

2) I found out that namespace ID 104 is from Semantic MediaWiki (which I have installed) but is no longer used.

3) So, it appears as though it is a bug related to SMW rather than pywikibot. It seems like the easy work around is just to create the 104 and 105 namespaces (unless they are already there [how do I find that out?]...and, being a newbie, I haven't created a namespace yet....more to learn!). What seems like the better fix, though, is to determine where pywikibot is picking up the namespace id's from and have it not search for 104 and 105. I'm now searching for that info, but if anyone knows that and can respond, I would appreciate it.

Thanks,
Bud
