Only occurs in latest version (0.6.07).

I just ran into this after upgrading from 0.6.06 to 0.6.07 -

duplicity --name BACKUP1 --full-if-older-than 1M --no-encryption --include-globbing-filelist filelist / file:///media/BACKUP1

In my case the workaround is to remove "-full-if-older-than 1M" and to specify a full or incremental backup explicitly.

I believe the problem is that in duplicity main(), commandline.ProcessCommandLine() is now called before dup_time.setcurtime(), so the curtime global is not set.

The patch resolves the problem for me. Thanks for the quick fix.
