Now the add_text.py script is working. My best guess as to why is that I had namespacealiases in cache that were incorrect and then the cache either expired or was overwritten.

Why I think that:

My debugging led me to the _build_namespaces function in site.py. It does two api calls to siteinfo.get. One to get the namespaces and one to get the namespacealiases. The second call then iterates through the result set looking for ['*'] in the namespace dictionary (returned from the siteinfo.get for namespace). It was here that the script failed. It was looking for namespace 104 (which doesn't exist on my wiki and did not get loaded into the siteinfo.get for namespace). For some unknown reason, it did get loaded into the namespacealiases dict.

In trying to determine what namespaces and namespace aliases were actually installed on my wiki, I queried api.php through my browser using this format: example.com/wiki/api.php?action=query&meta=siteinfo&siprop=namespaces&formatversion=2 and then again changing siprop=namespaces to siprop=namespacealiases. Both of these queries verified that neither namespace alias nor namespace 104 (and 105) exist on my wiki.

After executing these two queries, I added a couple of pywikibot.output statements in site.py to see if I could determine more info with what it is what retrieving in the siteinfo function. It was then that the script worked correctly. My guess is that executing the api.php query for namespacealiases refreshed the cache thereby removing the alias to ns 104. It's a total guess, but all seems to be working now.

Thanks again for your help.
Bud
