I haven't upgraded to 4.6.2 yet (I hope to tonite/tomorrow, 4.6.1 ATM, 
Gentoo), and in any case, I don't give my normal X/KDE user privileges 
enough to shutdown the system directly (I have the standard Ctrl-Alt-Del 
set to logout, no confirmation, which returns me to the CLI prompt as I 
don't run a ?DM graphical login utility, and then hit the power button, 
which sends an ACPI signal that triggers a switch to init-0, shutdown, or 
a second C-A-D, which from the CLI triggers a switch to init-6, reboot), 
so I wouldn't notice the issue even if I had upgraded.

However...

It's worth noting that kde 4.6 switched from hal to udev/upower for that 
sort of thing, mediated by policykit configured system privileges.  Since 
that infrastructure is new for 4.6, it's quite possible they are still 
tweaking it, and I'd suspect an issue with either the policykit configured 
permissions, OR upower (which I don't have a clue on at this point), OR 
the dbus mediated communication with polkit and upower.

As such, I'd probably check the policykit settings in kcontrol, near the 
top of my list.  Gentoo users will want to ensure they have the policykit 
USE flag turned on.  Etc.

That probably won't be a lot of help but hopefully it'll be a hint toward 
which direction to check, anyway. =:^\
