Winfried, would you please try the following change to line 620 in backup_gmail.py. Instead of this:
GMAIL_LOC = 'en_US'
please use this:
GMAIL_LOC = 'POSIX'
and see if it runs correctly using 'Okt' for your dd-MMM-yyyy. I had used 'en_US' because I had found documentation stating that this locale was invariably installed regardless of a user's particular locale choice, but this is apparently not the case. Now I see that 'POSIX' should be used for the purpose I had in mind.
