kdm component don't exist in the list, by that reason is filed against kdebase, also the problem will be elsewhere in pam or X

Description of problem:
This happen in Fedora 11 i586 (two machines)

At kdm login if entered a invalid password, when you enter the password ( correct or incorrect) by second time kdm crash taking Xorg with him

begin three differents logs of the crash:
