Comment 13 for bug 582720

I'm proposing that deja-dup 16.1.1 be approved as an SRU for maverick. 16.1.1 fixes three bugs:

 * Fix backing up to devices that don't report free space (LP: #657518). This means that some people who bought certain types of NAS devices can't back up to them at all. [Two line patch.]

 * Don't ask for root password if it's not needed (LP: #662884). This would prompt users for a root password if they were restoring to 'original locations' even if all their files were inside their home directory. By itself, not so bad, but it became much worse in conjunction with the next bug. [One line patch.]

 * Fix GPG Error during restore (LP: #582720). If you were restoring from an encrypted backup and deja-dup prompted you for the root password, you would afterwards get a fatal GPG error. The only workaround was to avoid a password prompt by restoring to a separate directory, not the files' original locations. [Ten line patch.]

These have all been fixed in deja-dup unstable and stable branches (17.1 and 16.1 respectively). 17.2 is in natty, 16.1.1 is in the upstream PPA: https://launchpad.net/~deja-dup-team/+archive/ppa

TEST CASE: For the first bug, I don't know how to reproduce without the device. But you can test the next two bugs together:
1) Make a backup to, say, ~/deja-dup-test, that contains just some simple home directory, like ~/Documents. Make sure it is encrypted.
2) Try to restore that backup to 'original locations'.
3) If you get prompted for the root password, you've hit the second bug. If you afterwards get a GPG Error, you've hit the third bug. Both should be gone in 16.1.1.

I'm not aware of any regression potential with the patch. I'm attaching the debdiff and uploading to maverick-proposed.
