With the latest master, if I send a message it appears to work (the message is not visible in my Outbox) but the message is never sent: it doesn't show up in Sent Mail in Gmail.

If I run 'geary --debug', the console shows errors like these:

 [deb] 08:16:32 0.000076 db-connection.vala:351: Connection.exec_transaction: transaction threw error: (Statement.ctor /home/adam/.local/share/geary/adam@ongoing.ly/geary.db) [err=1] - no such column: sent (

                    FROM SmtpOutboxTable
                    ORDER BY ordering DESC
                    LIMIT ?
                )

                )
