[Pkg-utopia-maintainers] Bug#738023: Upgrade libpolkit-gobject-1-0 and libpolkit-agent-1-0 breaks all PolicyKit agents

[программист некто]

Package: src:policykit-1
Version: 0.112-2
Severity: critical

Hello comrades.
Upgrade packages libpolkit-gobject-1-0 and libpolkit-agent-1-0 from stable (0.105-3) to experimental (0.112-2) totally breaks all PolicyKit agents.


$ /usr/lib/x86_64-linux-gnu/lxpolkit

** (lxpolkit:4329): CRITICAL **: polkit_agent_listener_register_with_options: assertion 'POLKIT_IS_SUBJECT (subject)' failed

(lxpolkit:4329): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

'Ошибка сегментирования' in English sounds as 'Segmentation fault'.


I have installed debuggins symbols and found that:

$ gdb -q /usr/lib/x86_64-linux-gnu/lxpolkit

done.

Do you need "set solib-search-path" or "set sysroot"?

I also check other PolicyKit agents:

$ /usr/lib/x86_64-linux-gnu/polkit-mate/polkit-mate-authentication-agent-1
(polkit-mate-authentication-agent-1:5803): polkit-mate-1-WARNING **: Unable to determine the session we are in: No session for pid 5803

Downgrade libpolkit-gobject-1-0 and libpolkit-agent-1-0 to stable versions solve the problem.
