Re: Unison not launching GUI

Dear Greg

I downloaded the binary for ubuntu and I tried to connect with my office 
machine and I get this messages:

Unison failed: Uncaught exception Failure("input_value: ill-formed message")

It is related to the issue that I have an old version on the remote machine?
