`join': no implicit conversion of nil into String (TypeError)

Howdy,

If I use the sitemap_generator.rb with either the monthly or category archives plugin, I'm getting the following error:

sitemap_generator.rb:78:in join': no implicit conversion of nil into String (TypeError)`

I'm not a Rubyist, but it appears that the site object contains the following array for pages when the monthly or category archive plugin is installed:

@pages=[#<Jekyll:Page @name="index.html">, #<Jekyll:Page @name=nil>]

Any thoughts on how to work around this appreciated. :)

Phillip.
