Do you use an automated script/hook to add your > S-o-B? I only use the --signoff flag to git-format-patch. It looks like the cause is that I have a hook to add a Gerrit Change-Id to my commit messages, and that hook added a blank line followed by Change-Id:blah after my original Signed-off-by line. Then git-format-patch added another Signed-off-by after the Change-Id. The Change-Id line was then stripped out by a wrapper around git-send-email.
