Panic on program start #8
Description
When trying to start fast-ssh from the command line using fast-ssh it fails and freezes the terminal, I am trying this on Fedora 34 and have tested both the downloadable tar.gz file from the latest release (v0.2.1) as well as via the cargo install fast-ssh method. I have run the command with RUST_BACKTRACE=full as suggested and have provided the output below.
EDIT: Downgrading to an earlier version (v0.2.0) fixes the issue.
$ RUST_BACKTRACE=full fast-ssh > backtrace
