> Yes, the password did change that way and was left as the old one
What do you mean? I really don't understand this sentence as its two parts sound antithetic to me.

My general idea is that users-admin hangs when 'passwd' fails with an error message we don't handle. Which doesn't seem to be the case here. Did you use the same new password? Are you able to reproduce the hang in users-admin? Have you tried with different values for the new password?
