Steps:

Bundle for OSX downloaded on 14-sep-2017.

create wallet with simplewallet -> OK . Finish (harshly; it won't exit gracefully)
open wallet with simplewallet -> OK . Exit (harshly; it won't exit gracefully)
open wallet with walletd -> OK. Exit.
open wallet with simplewallet -> FAIL.
Notice shasum of the wallet in step 1 is different than in step 4.

Simplewallet and walletd use different formats.

As a simple user I'd suggest...
Feature request: prevent crossed wallet smashing (at least launch a warning).
Thanks.
