I’m using the RFacebook for rails plugin and I have stumbled across an  
annoying problem when generating paths and links with url\_for and  
link\_to. It appears that when I, for example, call url\_for :controller  
=\> “pages”, :action =\> “new”, the return will be /canvas\_url/pages/  
canvas\_url/new. It happens similarly when :id is set, returning /  
canvas\_url/pages/canvas\_url/view/canvas\_url/1. Does anybody know  
what’s wrong? Has anybody else experienced this problem? I tried  
looking in the source of the RFacebook gem and came up with nothing.
