I don't know if anyone else has seen this but when trying to use the
code in recipes 15.8 and 15.9 of the Ruby Cookbook you get non-stop
Dispatch errors. Your application will throw ArgumentError 0 for 1
with every page request.
Has anyone else run across this? If so did you figure out what was
causing it? I've been staring at it off and on for about a day and
don't see anything. I ended up ripping it out of my top priority
application and replacing it with something else.
