Mongrel users - Sep 2006 - upload_progress and DRb.start_service crashes

Whenever I tried to start mongrel_rails with the upload progress  
script, it would die with the following error:

/usr/local/lib/ruby/1.8/drb/drb.rb:837:in `getaddrinfo'': getaddrinfo:  
No address associated with nodename (SocketError)
         from /usr/local/lib/ruby/1.8/drb/drb.rb:837:in

         from /usr/local/lib/ruby/1.8/drb/drb.rb:860:in `open_server''
         from /usr/local/lib/ruby/1.8/drb/drb.rb:756:in `open_server''

         from /usr/local/lib/ruby/gems/1.8/gems/gem_plugin-0.2.1/lib/

mongrel/command.rb:211:in `run''
         from /usr/local/lib/ruby/gems/1.8/gems/mongrel-0.3.13.5/bin/ 
mongrel_rails:234
         from /usr/local/bin/mongrel_rails:18


I fixed this by changing init.rb in mongrel_upload_progress - line 13  
needs to supply a uri :

       DRb.start_service("druby://localhost:0")


I suspect this is actually a bug in drb - the default uri probably  
shouldn''t crash the process.  And why isn''t everyone seeing
this
problem?

Is that even needed?  I''m not sure why that''s there, since
mongrel is
acting as the client.  The only line that should be needed is
DRbObject.new(nil, options[:drb]).  I''m using this right now though
and haven''t had issues.
