Generating patch is only part of the story, it seems the patch is not sent
properly and tags which should be in SMTP header end up in the message
body. I think there would not be such issues if you have used git format-patch
+ git send-email.

I normally do amend things like this while applying, I will do that this time 
as well. It's already too much time wasted for such a dubious patch.
