I noticed this issue with users-admin in the case I changed my password with a similar one.
Trying with passwd from the console I get:
#~$ passwd
Changing password for max.
(current) UNIX password:
Enter new UNIX password:
Retype new UNIX password:
Bad: new password must be different than the old one
Enter new UNIX password:
....
Trying with users-admin the button goes grey and just stays there waiting.
In this way the issue is easily reproducible.
