Non empty string complained to be 'nil' in equality check

I have the below code
response = Net::HTTP.start(url.host, url.port) do
|http|
http.request(request)
end
exp_code = 450
if(response.code.to_i != exp_code)
raise StandardError, “Expected #{exp_code} Received
#{response.code.to_i}”
end
exp_msg = ‘Blocked By Parental Controls’
puts ‘Received status msg: #{response.message}’
if(response.message != exp_msg)
raise StandardError, “Expected #{exp_msg} Received
#{response.message}”
end

The received response is
HTTP/1.1 450 Blocked By Parental Controls^M
Date: Mon, 12 Apr 2010 10:28:15 GMT^M
P3P: policyref=“http://p3p.yahoo.com/w3c/p3p.xml”, CP=“CAO DSP COR CUR

cache-control: public,must-revalidate^M
Content-Length: 0^M

^M

The “puts” statement is printing
Received status msg: Blocked By Parental Controls

But the next statement for inequality check fails with
can’t convert nil to string

However for a different case, where the response is
HTTP/1.1 200 OK^M
Date: Mon, 12 Apr 2010 10:28:29 GMT^M
P3P: policyref=“http://p3p.yahoo.com/w3c/p3p.xml”, CP=“CAO DSP COR CUR

cache-control: public,must-revalidate^M
Content-Length: 0^M
Connection: close^M
Content-Type: ^M
^M

and I have the ruby code as:
exp_msg = ‘OK’
puts ‘Received status msg: #{response.message}’
if(response.message != exp_msg)
raise StandardError, “Expected #{exp_msg} Received
#{response.message}”
end

Here there is no nil problem.
I have been breaking my head and don’t have the slightest clue what is
happening. Can somebody please shed some light?

goddammit, i was fooled because the if statement was teh last statement
in the code. The error didnt happen there at all. This code is a Ruby
testframework code so it supposed to return a true/false and I was not
returning, and that has caused the cruelly meaningless error message.
sorry for wasting everyone’s time.
