I think I ran into this problem and worked around it by making my
template at a higher level that avoids pagelink. Here's the Mako code
I use to generate a paged region with a navbar on top and bottom.
Note that Mako uses the pager object only for the records and page
numbers, and generates the URLs itself using h.url_for in the normal
way. There's some support for Ajax ('partial' parameter) but I'm not
using it so I'm not sure it's fully working.

## ************ PAGED REGION *******************
<%def name="paged(page, whats, route_name, query_params)">

"""Put a paged section on a webpage, with links to the other pages.
page: A Page object from Christoph Haas' 'paginate' package.
whats: A plural word describing the elements in the page.
route_name: Name of route for URL generation.
query_params: Dict of query params for URL generation.
Your controller action should look for the 'partial' query parameter.
If present, return the paged region indicated by its value rather than
the entire HTML page.
