I'm having this problem too. Installed KDE 4.3 this morning and noticed the problem a few hours later.
I've found a workaround in http://www.phoronix.com/forums/showthread.php?t=15162 Just add
TerminateServer=true
in /etc/kde4/kdm/kdmrc in the [X-:*-Core] section,
[X-:*-Core] AllowNullPasswd=true AllowShutdown=All NoPassEnable=false NoPassUsers= ServerArgsLocal=-br -nolisten tcp ServerCmd=/usr/bin/X TerminateServer=true
After this, KDM works as expected, but I don't know if this can cause side effects.
