Ola, any change you can look at this?

Every step toward getting Net::SSH working makes me happier.

Reproduced locally, and users asking for this on IRC too

FYI, when I looked at this last fall, the problem appeared to be in Cipher.java, but I wasn't able to determine exactly what it was doing wrong. Unfortunately, I haven't had (and still don't have) time to revisit this, but see my notes at ~~JRUBY-1692~~. The error message is a little different than what I was getting, but I suspect it is the same issue. I found the :verbose => :debug option somewhat helpful in tracing the calls, and Cipher.java has a DEBUG flag that can be set to provide additional info.

This was fixed together with the other SSH bug. It was the IV-problem documented there.
