Re: Strange error with no stack trace
Wow, thanks Magnus. Adding that certainly made the output more interesting: http://pastebin.com/DSMKWK52 As you can see, the ruby version seems to be 1.8. It can be bumped up to 1.9 I believe if this is preferred? drinking.rb line 127 is simply: render :index The plot thickens...

Re: Strange error with no stack trace
My gem file reads thus:
gem "activerecord", "3.0.3"
gem "camping", "2.1"
gem "nokogiri", "1.4.4"
gem "rest-open-uri", "1.0.0"
gem "sqlite3-ruby", "1.3.2"
gem "tilt", "1.2.1"
gem "haml", "3.0.25"
Will get the ruby version asap.
Love the idea of adding the method! Great!

Re: Strange error with no stack trace
Hm…
Like Dave mentioned, could you give us the versions you're using? For
both Camping, Rack, Tilt, Haml and Ruby? Also, you could add this
little snippet to "force" a backtrace:
class NilClass
def to_sym
puts "NilClass#to_sym:"
caller.each do |line|
puts " #{line}"
end
raise
end
end
Maybe that gives you any clues!

What version of ruby is Heroku running?
