Btw, same behaviour seen with "tmkms softsign". I suppose this might also relate to ledger, but compiled without ledger support.
It's an Abscissa bug. PR to fix it here: iqlusioninc/abscissa#106
(note: the code for displaying usage info in Abscissa is a bit gross right now and I intend to rewrite it all soon, which among other things will make it easier to test)
Fixed upstream
