Well, this was a submitted patch, I don't know a lot about it, so take
this with a grain of salt.

I assume you're seeing a value for 'hostip' and 'hostmanc' on the
leases in question (or else null values would be pretty obvious).
On a hunch, try placing the binary-to-ascii() calls directly inside
the execute() arguments instead of using the binding scopes.

This is unfortunately an intentional design.
