Duplicate gmail messages with X-TUID

[Myles E. <myl...@gm...>]

Hello,

Can anyone tell me how to further debug this problem please?

Old messages are being synced back to my gmail AllMail with new
timestamps but retaining the seen flag.  Checking the local Maildir
there are indeed duplicate messages that differ only in a line
containing a X-TUID such as:

$ diff /home/myles/Maildir/mygmail/cur/1383659015_1.25732.bill,U=9303,FMD5=7e33429f656f1e6e9d79b29c3f82c57e:2,S /home/myles/Maildir/mygmail/cur/1343727355_2.3529.bill,U=1159,FMD5=7e33429f656f1e6e9d79b29c3f82c57e:2,S
38d37
< X-TUID: olHgdEn8UseN

The .mbsyncrc looks like this:

IMAPAccount gmail
# Address to connect to
Host imap.gmail.com
User my...@gm...
Pass xxxxxx
# Use SSL
UseIMAPS yes

IMAPStore gmail-remote
Account gmail

MaildirStore gmail-local
Path ~/Maildir/mygmail/
Inbox ~/Maildir/mygmail

Channel gmail-inbox
Master :gmail-remote:"INBOX"
Slave :gmail-local:

Channel gmail-orgmode
Master :gmail-remote:"orgmode"
Slave :gmail-local:.orgmode

# Get all the channels together into a group.
Group gmail
Channel gmail-orgmode
Channel gmail-inbox

This command syncs:

mbsync -V -Cs gmail

This Maildir has previously been used with dovecot and offlineimap if
that makes a difference.  I am using the git repo as of 9 Nov, commit
44daf186b on Arch Linux.

Thanks,

Myles
