What version of Ruby are you using?

In the first same looks like you're using ruby builtin Net::SSH
support, but dunno if shell is being part of a Session instance.

On the second example, looks like it even worse, but looking at the
line numbers (95!) seems you have a huge script.

Can you reproduce the problem in a small one and pastie it to us so we
can trace it? (try providing the full backtrace to ease the task).

Thanks,
