Bug#569058: helper not setuid; breaks gnome-power-manager

[Joey Hess]

Package: dbus
Version: 1.2.20-2
Severity: normal

gnome-power-manager is not working, devkit-power has the same
problem:

(devkit-power:10045): devkit-power-gobject-WARNING **: Couldn't enumerate 
devices: The permission of the setuid helper is not correct

Is this supposed to be setuid?

-rwxr-xr-x 1 root root 39K Feb  3 22:19 
/usr/lib/dbus-1.0/dbus-daemon-launch-helper*

Downgrading dbus to testing fixed it for me:

-rwsr-xr-- 1 root messagebus 39K Jul 15  2009 
/usr/lib/dbus-1.0/dbus-daemon-launch-helper*

Then I re-upgraded, and the permissions were preserved.

Two possibilities:

1. Btrfs, which I use for my root filesystem, is more experimental than
   expected and somehow responsible for the lost suid bits and group
   ownership. Possible, but seems unlikely.
2. Somehow dbus.postinst's chown failed. Maybe I had a dpkg-statoverride
   entry for the helper from before (if so, I had not added it manually,
   and I don't have it now).
