found 851317 0.6.3-4 thanks Hi.
Sorry for the reopening but this issue does not seem to be fixed in version 0.6.3-4. See this for example: https://tests.reproducible-builds.org/debian/rbuild/buster/amd64/ruby-sidekiq-cron_0.6.3-4.rbuild.log.gz (And I also still get the same error randomly in my own autobuilders). Thanks.
