[Pkg-utopia-maintainers] Bug#846230: policykit-1-gnome: Fails to start with warning: "Unable to determine the session we are in: No session for pid"

[Gianluca Guidi]

Package: policykit-1-gnome
Version: 0.105-5
Severity: important

Dear Maintainer,

I use lightdm and Xfce.

The agent is not started on start
up, so many functions do not work, such as controlling network through
NetworkManager, mounting disks with Nano, running Gparted, powering off
or suspending through Xfce's log out panel and possibly others.

I tried starting polkit-gnome-authentication-agent-1 manually, but the
process closes/crashes immediately, reporting the following message:

(polkit-gnome-authentication-agent-1:7502): polkit-gnome-1-WARNING **:
Unable to determine the session we are in: No session for pid 7502

I read several threads on the internet describing similar issues, but
they none of them helped in solving the issue or identifying its cause.

This problem presented itself after a recent update. I think that the
package itself was not updated, however this is my best bet on where
to report this bug.

Please let me know if I should provide more information.
