The bug itself is:
Why are the headers not being updated correctly per the changes I made to Compose > Headers (as shown in the image at http://imagebin.ca/view/qjHzvM.html and soon to be attached to the bug report)

Long story short, my emails at work were being rejected by a ticketing system.  I looked into the issue and it seems that my KMail Headers were giving this:

> Content-Type: multipart/signed;

when I would sign with a GPG key, and as

> Content-Type: Text/Plain;

when I wouldn't sign.  Either way I was being rejected by the system, and I never sent any HTML-formatted emails at all.  Other people's emails were showing, in lowercase:

> Content-Type: text/plain;

I changed the custom headers per this image:
> http://imagebin.ca/view/qjHzvM.html
and my headers are pretty much the same, except:

1.  My work's ticketing system is no longer rejecting me, no matter how much HTML etc I put into an email, and

2.  The changes aren't actually happening in the headers for new emails, and I don't know why nor do I know why the system would start accepting my emails.

What would be different?  Here are the headers themselves:
