I don't know the reason for this crash. Could you send me all tinc's log
messages from that day to me privately? That would help me debug the problem.
I do not think upgrading to 1.0.20 might help in this case. You might want to
try 1.1pre6 though, since that is different enough that this bug might not
appear.
