OEmbed::Formatter::JSON.backend::ParseError is nil

[panzi]

For some reason ::ActiveSupport::JSON.parse_error is nil at the point where it is assigned to OEmbed::Formatter::JSON.backend::ParseError and thus you get strange exceptions later. I use Rails 2.3.

Maybe it would be better to change it to a method that reads ::ActiveSupport::JSON.parse_error whenever it is called?

Currently I fix this by adding this initializer:
module OEmbed
module Formatter
module JSON
module Backends
module ActiveSupportJSON
if ParseError.nil?
remove_const(:ParseError)
if ::ActiveSupport::JSON.parse_error.nil?
ParseError = StandardError
else
ParseError = ::ActiveSupport::JSON.parse_error
end
end
end
end
end
end
end

Interesting. Thanks for reporting this!
