Trying to do SOMETHING to close in on this error message, I made the 
following modifications to the app.py file, just before line 87 where the 
error was occurring when the call to page_enter occurs:

    def set_page(self, name, *args):
        if self.locals.__page__ \
           and self.locals.__page__ != name:
            self.app.load_page(self)
            self.app.page_leave(self)
        self.locals.__page__ = name
        self.app.load_page(self)
        ######## debugging code #########
        f = open("alb-debug.txt", "w")
        f.write("*args is %s" % str(args))
        f.close()
        ####### end debugging code #######
        self.app.page_enter(self, args)

Then I look in the alb-debug.txt file after running the application and 
getting the same traceback. Contents of the file are as follows:

*args is ()

exactly, mind you. No leading or trailing whitespace of any type.

Now the call where this occurs is:

self.app.page_enter(self, args)

so the only way I can see three parameters being passed here, is if the 
page_enter function is interpreting '(' as one argument, and ')' as a 
second argument.

This is very bizarre. :\
