Dear Maintainer,

In a package (tails-installer, currently in Debian NEW queue), we use
polkit to ask the user for authorization to rewrite the MBR of a USB
stick and to use syslinux. When the screen locker is active though, the
authorization window asking for the root password overlays the screen
locker window.

I'd have expected that this window would not appear over my locked
screen, but only be accessible only when the screen is unlocked.

Not sure if this bug report should go against Gnome screen locker instead?

Cheers!
