"gpg: can't handle text lines longer than 19995 characters" error when backing up

[Robin Sheat]

When I run deja-dup, and it encounters some data* it asks for the password to be reentered, and when you do that, it tries again, and gets in the same loop, over and over until you cancel. Nothing ends up being backed up.

* e.g. my gpg public keyring, but when I exclude .gnupg, it has what may be the same problem on something else too, so I think that's coincidence.

The last part of the log is at the bottom of this, and I'll attach the final 1000 lines. I don't think this is a duplicate of bug #883742, as the source of the error is quite different.
