I like how Net::SSH2 works with channels and subsystems, a cursory look at Net::OpenSSH does not reveal much on that but I will take a closer look.

Net::OpenSSH does not expose the Channel concept to the user. It gets hidden behind higher level and more familiar abstractions (i.e. processes, pipes, redirections, etc.).

Still is very odd that many Unix flavors work just fine and just Fedora has an issue...

Net::SSH2 and the libssh2 library are not mature yet and critical bugs still pop up now and there... though, they are active projects so try to write a minimal script reproducing the error and send it to the module author.
