Rack::Lint::LintError - wrong Content-Length

[ixti]

Not sure what cause this problem, but sometimes I have this error:

Difference between expected length and actual is also different from time to time. Error appears on any page, but only sometimes, in other words it appears randomly and I can see it ONLY in log output when RACK_ENV=development.

My ruby version: 1.9.2-p180
