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!
