Yeah, I saw that. This is my fault and has nothing to do with
offlineimap.

What happened is that before sending the email to the list I saved it as
a draft and tested the offlineimaprc to make sure it worked (I added
some comments). I accidentally called a script that automatically tags
my email, and it tagged the draft. When I sent the draft, with msmtp
(did not pass through offlineimap) it was sent with the X-Keywords
header. I should fix that ...

This patch already implements a feature to strip out the X-Keywords
header when moving a message from local to gmail.
