I should have verified before emailing, that's the old, old version packaged 
for Debian 10 (Debian 11 will come with 20210822).

However, I can reproduce it still with the latest release:

$ printf 'foo\0bar' | parallel -0 -S 1/examplehost --filter-hosts echo {}
parallel: This should not happen. You have found a bug. Please follow
https://www.gnu.org/software/parallel/man.html#reporting-bugs

Include this in the report:
* The version number: 20220622
* The bugid: nsockets missing: localhost
* The command line being run
* The files being read (put the files on a webserver if they are big)

If you get the error on smaller/fewer files, please include those instead.

Switching to newline-separated input as the workaround still avoids the issue.
