[erlang-bugs] Error on running Erlang SSH server

[Arif]

I have tried to replicate the problem and it is as Tony suggested: 
system_dir in the list of user_passwords ensures system_dir is not set.
There are either no host keys in the default directory as Daniel's reply 
suggests or if they are, they are not readable.
The bug, if any, would be the somewhat misleading error message with a 
request to report it to this mailing list.
Regards
Arif
