On gaia-11001 I see the same behaviour. There is an inconsistenty between just giving --ledger and --ledger --from="test_ledger. I would expect that using those two flags should produce the same error messages.

Are you sure there has been a transaction involving it?

The first error message ERROR: No account with address was found in the state. must be wrong.
I am sending from this account

My current thinking is that this error is caused since an account that is backed by a Ledger hasn't had its pubkey revealed. Maybe that's why it can't find the address in the state. However I am certain that the ledger account has a balance.

[jleni]

The root cause is that when the account is created, gaiacli is not correctly storing the derivation path in the keybase.

Any command that later refers to these ledger keys, fails because a derivation path 0/0/0/0/0 is sent to the ledger and it gets rejected.

[jleni]

I will now prepare a fix plus additional unit tests for the keybase store/restore functions.
And some additional checks to the keys add command in the CLI.
