Insync show exception

Hello, when I’m doing insync show I have this error:

Exception happened during processing of request from 
Traceback (most recent call last):
  File "SocketServer.py", line 593, in process_request_thread
  File "SocketServer.py", line 334, in finish_request
  File "isyncd/linux/portable/unix_socket_server_portable.py", line 111, in __handler
  File "isyncd/linux/portable/unix_socket_server_portable.py", line 128, in _handle_linux_simple_api
TypeError: 'NoneType' object is not iterable

I think it’s a unix socket file that’s missing. If so, where should it be created?

Regards
