Log Out: "Error reloading your Gravatar" after logging out

Quite often (but not always) after logging out I see an error pop up that says:

Error reloading your Gravatar

Steps to reproduce:

1. Go to Me > Log Out.
2. Check to see if a Gravatar-related error pops up.
3. You may need to re-try a few times.

Start by reproducing the issue from Me > Log Out on the WordPress Android app and review the Gravatar loading failure alongside the sign-out log sequence. Trace what triggers the "Error reloading your Gravatar" message during logout; done means logging out no longer shows that error, including after repeated attempts.
