Hm, I tried to change my password to "foo%bar", and was able to authenticate with it. When I mistype the password, I get auth.log entries similar to your's.
So I cannot reproduce this bug. Can you please do
POLKIT_DEBUG=1 users-admin 2>&1|tee /tmp/debug.log
then try to authenticate, and after that, send me /tmp/debug.log?
