Occasionally, and with no apparent correlation with what is going on on other devices where I have Messages enabled, I get a negative count for my unread messages in Messages on OS X:

What could be causing this, and how can I prevent from happening in the future?

I can't help with a solution or workaround but this is clearly a bug and you should report it: – Matteo Sep 30 '12 at 19:03
I'm stuck at 1 (positive) unread message, despite having read all messages. Clearly bugs here. Thanks for reporting. – duozmo Dec 23 '12 at 23:08

I believe that negative numbers show up when you read a message on another device before you read it on what ever device has the negative number. I had the same thing happen to me. I have a "-1" badge on my Messages icon.
