After update to 4.3.5 there is no options "Poweroff" and "Reboot" in Exit Session's dialog.
How are you logging in? GDM? KDM? Something else?
and the usual,
rpm -q kdm gdm kdebase-workspace
As well as, from the session not showing poweroff/reboot, post output of:
qdbus --system org.freedesktop.ConsoleKit \
rpm -q tigervnc-server freenx
If either of these are installed, it's likely due to
bug #561905 (freenx)
Method "CanStop" with signature "" on interface "org.freedesktop.ConsoleKit.Manager" doesn't exist
but i don't use selinux

Grrr, this is my fault, I thought CanStop is supported in all supported Fedora versions by now, it turns out it's only supported from F12 upwards. I'll fix F11 to disable that check again. Sorry for the breakage.
