[scponly] segfault when trying to connect

[Kaleb Pederson]

Thanks for trying Tim.

I have attached a patch that will hopefully help us figure out about where 
it's failing...

Feel free to add in other debug code similar to what I have attached that 
might help us figure out where it's segfaulting.

Thanks.
