The upcoming findutils-4.2.25-1 (whenever upstream releases 4.2.25)
better documents this. -i is being deprecated in favor of POSIX -I, which
requires an argument, whereas the non-standard -i treated its
argument as optional. So what may be happening (although you'd
actually have to debug to see for sure) is that -i -n treats -n as the
string to replace, instead of the default {}. But that sounds odd, and
it may be an upstream bug; I'll investigate further.
