Comment 39 for bug 989496

I'm runnin ubuntu 12.04 with duplicity 0.6.20(but had same error with duplicity 0.6.18 and 0.6.19) and had same problem. I do backups on webdav.
duplicity --include-globbing-filelist /etc/backup-files.txt / webdavs://login:<email address hidden>/Bakeups/nightserv/
Чтение подстановочного списка файлов /etc/backup-files.txt
Локальные и удалённые метаданные синхронизированы, синхронизация не требуется.

But with LANG=C it works pretty well:
LANG=C duplicity --include-globbing-filelist /etc/backup-files.txt / webdavs://login:<email address hidden>/Bakeups/nightserv/
Reading globbing filelist /etc/backup-files.txt
Local and Remote metadata are synchronized, no sync needed.
