argument must be 9-item sequence, not None

Initial backup gets to 50% and then errors out and program must be killed:

I'm also getting this. The first time I saw it, I re-ran the backup with the same parameters and it then worked. The second time I ran into it, it didn't work the second time.

I have:
  From: 01-Jan-2009
  To: 31-Dec-2009
  Keep read/unread

no labels were specified, and I did *not* choose an incremental backup.

Also getting this. I run backup_gmail in console without any parameters, just entered folder, e-mail and password.

[Michael Schievelbein (hu6-michael-t16)]

I am also receiving the same error.
I found out by using the Include option and playing around that there appears to be a limit of 9 labels on the account.
If you Include the labels <9 at a time, it works.

[C Fraire (cfraire)]

Michael, there is no limit on the number of labels. The error is due to a message in your account that has no "Date:" which for you is being excluded when you run with a smaller set of labels.

wenjoseph fixed this in trunk revision 6. The Downloads for this project do not reflect the latest trunk code. You can get trunk revision 6 versions of backup_gmail.py and gui.py by browsing the code.
