No, but I just accidentally discovered that if I attempt to login with
an incorrect password, and get kicked back to the login prompt with a
"password incorrect" error, the next login with the correct password
will succeed. Then if I logout and attempt to login with a correct
password again, a segfault again.

A work-around, at least. So I would be alright if you downgraded the
severity from "important" to "normal".
