The development version of duplicity crashes when --exclude-older-than is included on the command line. The following trackback is from 0.8.03, although 0.8.07 behaves the same way. 0.7.19 works OK.

I am using duplicity under openSUSE Tumbleweed, 20191119 snapshot, Python 2.7.17.
The traceback says you are running Python 3.7, not 2.7. Plus, it looks to be from an older version of duplicity. Please uninstall all versions of duplicity, especially those from the repo, then reinstall from one of the ones below. "sudo apt uninstall duplicity"
Do a 'which -a duplicity' to find if multiple versions are installed. Remove all. Look in /usr/lib64/
* Release tarball Install - https:/
* Daily duplicity builds - https:/
* Stable snap builds - “sudo snap install duplicity —classic"
