Awesome addon, but not usable any more Rated 3 out of 5 stars

After few amazing days with this addon, it stopped working, it is not possible to reply to emails AT ALL. when I disable it, the mail gets send without a problem. When it's enabled, it hangs at "delivering mail" and then I get this:
"Sending of message failed. The message could not be sent because the connection to SMTP server smtp.gmail.com timed out. Try again or contact your network administrator."

conversations 2.5.2, thunderbird 14, linux mint debian,
please help because your addon is really really useful

edit:
it's a duplicate of a reported bug (having image as a signature): https://github.com/protz/GMail-Conversation-View/issues/644

This review is for a previous version of the add-on (2.5.2). 

Can you head over to the bug tracker at https://github.com/protz/GMail-Conversation-View/issues and open an issue there? Thanks, jonathan
