crafh of daemon sometimes

[Attila Balint]

Its just a hunch but I'm guessing that a thread is created as a receiver
and that reads the the socket. The socket was created as blocking and when
you stop the process it exits this state and there is no check that there
was an actual message received and it tries to decrypt a message. I haven't
looked at the code but .... :D
