Well, showaq didn't seem to be showing anything wrong, but in the course
of writing out a more detailed description of my symptoms, I discovered
the actual cause of the problem:
Here is how I had defined the PTFile:
index_html = PageTemplateFile('www/weblogLibrary', globals(), __name__ =
When it needed to read:
library = PageTemplateFile('www/weblogLibrary', globals(), __name__ =
Everything works fine now.
Note: Although things are now functioning correctly, I am still seeing

In other words, the id of the 'library' PTFile is not being displayed by
the showaq method. Any ideas why (and whether this is in fact a
