object not selected, just free view, press o key at invalid position.

"Can't add : invalid position"

Even if you don't select any objects and press O, lfs interprets it as a message anyways. (PMO_POSITION, see InSim.txt PMOAction enum). People can use this information in their InSim's to teleport people into the pointed location, for example. So, it is completely normal for this message to appear even if you haven't selected an object because you don't have to select one.
