In the RandomPageModuleMixin the code traps an ImportError when it
tries to load the page module.  It assumes that the request page
module was the module which could not be loaded.  This is a bad
assumption it seems :-)

Looks like the only was around this is to modify the code

        try:
            self.load_page_module(ctx, page)
        except ImportError:

to this

        try:
            self.load_page_module(ctx, page)
        except ImportError, e:
            if not str(e).endswith(page):
                raise

This unfortunately relies on the formatting of the ImportError
exception.

I am going to add code like the above into Albatross.
