#80too-vague error message when visiting a non-existent patch
I think http://hub.darcs.net/Aditya/darcsden-import/patch/2013092111223-ae6212 got obliterated and no longer exists. In this situation seeing a 404 would be better than "Sorry, fetching this patch timed out (or there was some other error)."
