I can confirm the presence of this bug in Kubuntu Jaunty. The problem only manifests when using passwords with non-alphanumeric ("special" characters) characters. Synaptic starts a kdesudo dialog which asks for the password, but fails to accept it. Starting synaptic from the command-line (sudo synaptic) works as expected.
