Ok, I got it. You can repro like this (replace "Iaggo" with you char name):

Code:
/script local function f(info) message(table.concat(info.rval, " ")) end; LibStub("LibRpc-0.1"):RemoteCall("Iaggo", f, "UnitArmor", "player")
Uploading fix now. It also includes some non-functioning code for setting remote events. That part is in progress.
