Perhaps the problem was in the wrong password

Yes it was:

(monitor.ml.Error
   "Could not read privkey-path /root/keys/my-wallet\
  \nwhile decrypting /root/keys/my-wallet: password is wrong or ciphertext is corrupt\
  \n"
  ("Raised at file \"lib/secrets/keypair.ml\", line 16, characters 2-99"
    "Called from file \"src/deferred1.ml\", line 17, characters 40-45"
    "Called from file \"src/job_queue.ml\" (inlined), line 131, characters 2-5"
    "Called from file \"src/job_queue.ml\", line 170, characters 6-47"
    "Caught by monitor coda"))

Keeping this open so we can replace the crash with a good error message!
