I don't know, I tried to re-create your issue locally, with the attached
script, and I don't get any error message, and the socket file and its
directory I create aren't backed-up:
$ tree /var/tmp/snap

This is with 2.0.0 on Fedora 32. Which version(s) are you using on which
OS(s)? There was an issue covered by a test called test_long_socket_name
in testing/longnametest.py. You're actually rather far away from the
limit of 107 characters, but it could still be your issue. Sockets are
IMHO not worth being saved so you could use `--exclude-sockets`.
