It's the Perl module, which on line 2256 is assuming that a slash simply
must indicate an X11R3-style Unix socket (DISPLAY=unix/localhost:0). Sadly
there's no maintainer, and the bug is filed at least twice (#39569 in
general, #41886 specifically for cssh). In the meantime, I may be able to
come up with a patch, just not immediately.
