If you follow that discussion chain, you'll see that there was a commit 
pushed for sshkit 1.3 that supposedly fixed the bug in question. However, 
either the fix doesn't work or rubygems *still* hasn't updated with the 
patched version over a month later. Not sure which is the case, as I 
haven't had a chance yet to pull down the github-hosted code and try it.
