in thread read gmail and extract cc field

Then something in your code is bad, as ->parse_headers is documented to return a hashref in Mail::IMAPClient.

Are you sure you are using a valid message id?

Maybe you can show us a short but complete example of how you are using ->parse_headers and how you obtain the message id.
