I have problem with receiving emails after upgrading to the latest stable version 4.1.1.

Even if I have setup that email should be parsed as plain text, issues are created with the text and there are unwanted

tags even if I setup text formatting to none or textile or markup.

This happens after updating to the version 4.1.1 from 3.4.13.

This is my environment:
