Steps to reproduce the problem:
I have password sync on, encrypted with a password so you can't view at passwords.google.com, but you should be able to view in chrome://settings/passwords

What is the expected behavior?
Passwords sync correctly

What went wrong?
Passwords do not sync, only on this device. I have tried apt-get purge, but that didn't do anything. chrome://sync-internals shows MergeDataAndStartSyncing@../../components/password_manager/core/browser/password_syncable_service.cc:364, datatype error was encountered: Failed to get passwords from store.

Passwords and all other data sync correctly across all other devices. All other data except passwords sync correctly across this device.

Did this work before? N/A
