Poezio is a console XMPP client. http://poez.io/
It has an OTR plugin. It seems to work with Jitsi...but when it sends a *long* message, or sends any message after leaving the OTR session open for a long time, Jitsi displays the ciphertext instead of the message.
I'm not sure whether this is a Poezio bug or a Jitsi bug, so I'm reporting it in both projects.
