Ac2git dando error de atributo

Estoy tratando de usar ac2git para convertir mi Accurev Depot a Git Repository. Seguí los pasos dados aquí: https://github.com/NavicoOS/ac2git . Recibo este error cuando trato de ejecutar el command python ac2git.py y la operación se cancela:

2016-08-24 09:07:31,312 - ac2git - ERROR - The script has encountenetworking an exception, aborting! Traceback (most recent call last): File "ac2git.py", line 3596, in AccuRev2GitMain rv = state.Start(isRestart=args.restart, isSoftRestart=args.softRestart) File "ac2git.py", line 2974, in Start self.RetrieveStreams() File "ac2git.py", line 1537, in RetrieveStreams endTr = endTrHist.transactions[0] AttributeError: 'NoneType' object has no attribute 'transactions' 

Usé el método como deep-hist y start_tran como 1 y end_tran como "ahora". Revisé el historial de accurev y hay una transacción en el n. ° 1, entonces, ¿a qué podría estar refiriendo el "NoneType"?

ac2git.config.xml

Como se comentó, parece que tuviste un error tipográfico en tu nombre de transmisión / depo
