Works fine if I just use the gem from rubygems.org. Unfortunately the optional parse options weren't available from there so tried out master.

btw if you proceed despite the error and use the bot, it will still work just fine. Note sure that triggers the error, and it's inconsistent - happens sometimes; gone after restarting the computer.

also seeing this on a fresh lita install, no changes made yet besides adding redis configs. it didn't happen the first ~2 times I started lita, then after that it comes up on every start

seedalpha/slackbot@0c790fe references the same error, it probably is easily fixed

[jimmycuadra]

Are you all still seeing this problem? I'm betting it was addressed by the recent fix to stop Lita from receiving other bot messages.

[eligiblekeng]

I don't see it anymore.

Actually can confirm this problem present on 1.8.0 version
