--- Comment #8 from Andrew Nguyen arethusa26@gmail.com 2009-03-05 17:40:49 --- The lack of the TcRegisterClient stub should not be a problem, as the client starts for me with today's Git and 1.1.16. The unimplemented stub should be rectified however. More likely your problem is that your working directory is not set to the program's directory, causing the divide by zero exception.
