I'm using the latest version of JabbR, Hubot 2.6.5, lastest of hubot-jabbr, latest of njabbr with version 2.27.0 of Request.

Any ideas of how to fix this?

Can you try to apply this patch and see if it resolves? I don't have a Windows box to test against the latest version of JabbR, so I've been using jabbr.net and do not get your error.
