deja-dup ignores passwords repetitively - no backup possible

[Wolf Rogner]

Preset:

After a full backup (with passwort protection set), deja-dup cannot create incremental backups.
It asks for the password, scans files, then asks for the password again.

First described in #1604811 (falsely relating it to duplicity).

After the password dialog appeared, deja-dup says:

Preparing ...
Scanning ...

asks for the password again.

One can break this loop only by cancelling the backup.

No backups possible.

OK huh. So duplicity does work with the same password, but deja-dup doesn't.

Do you know how to reproduce this situation?

[Vej (vej)]

This might be caused by bug #918489. Are you able to reproduce the problem with a backup created under 34.2-0ubuntu1.1 or later?
