Deja-Dup fails with "Failed with an unknown error" (Memory Error)

Using Deja-Dup 37.0/Duplicity 0.7.15 on Fedora 27. It fails right after boot just after receiving the "Starting Scheduled Backup" message with "Failed with an unknown error" and the following traceback:

Description: Fedora release 27 (Twenty Seven)

rpm -q deja-dup duplicity:
deja-dup-37.0-1.fc27.x86_64
duplicity-0.7.15-1.fc27.x86_64

So far I'm unable to reproduce the problem manually with DEJA_DUP_DEBUG on as requested.

I have a similar problem, I get the same Memory Error at the end. I have fresh install of ubuntu 17.10, using an external hard drive with previous backups on it.

This bug has plagued me for a while. I'm backing up to a remote system via SSH. Fedora 27 with packages:

$ rpm -q deja-dup duplicity
deja-dup-37.1-1.fc27.x86_64
duplicity-0.7.16-1.fc27.x86_64

Hello Tim and ausboffin.

Are you also unable to reproduce this bug with the following command-line?

DEJA_DUP_DEBUG=1 deja-dup --backup | tail -n 1000 > /tmp/deja-dup.log

Please set state back to Confirmed after answering!

Thanks

Vej
