remote/local folder creation fails

[Andreas Fink]

Hello,

I hit an odd bug, when trying to sync with offlineimap-6.4.2. Here my config:
[general]
accounts = gmail
maxsyncaccounts = 5
pythonfile=~/.offlineimap/offlineimap-helpers.py
socktimeout = 90

[Account gmail]
localrepository = gmaillocal
remoterepository = gmailremote
autorefresh = 2

[Repository gmaillocal]
type = Maildir
localfolders = ~/.mail_offlineimap
sep = /

[Repository gmailremote]
type = Gmail
remotehost = imap.googlemail.com
remoteusereval = get_username("gmail")
remotepasseval = get_password("gmail")
ssl = yes
port = 993
-------------------------------------- End of config-
-----------------------------------------------------


I've got an error on syncing which basically says:
Account sync gmail:
 *** Processing account gmail
 Establishing connection to imap.googlemail.com:993
 Creating new IMAP folder '' on server gmailremote
 ERROR: Creating folder Archived on repository gmaillocal
  Folder ''[gmailremote] could not be created. Server responded:
('NO', ['[CANNOT] No folder name given. (Failure)'])
 ERROR: Folder ''[gmailremote] could not be created. Server responded:
('NO', ['[CANNOT] No folder name given. (Failure)'])
 *** Finished account 'gmail' in 0:01
--------------------- End of
error1-----------------------------------------------------------


So I was thinking that I just start over, and download it once
completely again, but then I get two error messages, where the first
one is:

Account sync gmail:
 *** Processing account gmail
 Establishing connection to imap.googlemail.com:993
Folder Archived [acc: gmail]:
 ERROR: Aborting sync, folder 'Archived' [acc: 'gmail']
  getfolder() asked for a nonexisting folder 'Archived'.
Folder INBOX [acc: gmail]:
 ERROR: Aborting sync, folder 'INBOX' [acc: 'gmail']
  getfolder() asked for a nonexisting folder 'INBOX'.
[[Cut out of all the other folders I have on my gmail account]]
------------------------------- End of error2
------------------------------------------------------

and running it a second time gives the same error as above (i.e. it
tries to create an empty folder on the remote side)

Commenting the line "sep = /", and starting all over again still gives
the strange error2, that the folder is nonexistant locally (of course
not, I just wanna start syncing for the first time), but the second
sync starts and it seems as it would work (didn't test it fully, since
I really want to have a slash as separator)

So what am I doing wrong?

Cheers
Andreas
