[Savannah-hackers] lsh crashed - core available

[Loic Dachary]

        Dear doctor,

        lsh crashed once again. This time it dumped a core. I hope
you can cure it from its disease, it makes everyone a bit edgy :-}

Core was generated by `/usr/local/sbin/lshd --enable-core --daemonic 
--ssh1-fallback=/usr/sbin/sshd --'.
Program terminated with signal 6, Aborted.
