Description Eric Anderson 2010-05-22 22:13:09 UTC

Today I compiled and ran gnome-lirc-properties-0.5.0 on Arch Linux. I received the following exception:

Traceback (most recent call last):

dbus.exceptions.DBusException: org.freedesktop.PolicyKit1.Error.Failed: Error parsing subject struct


I corrected the exception with the help of http://hal.freedesktop.org/docs/polkit/eggdbus-interface-org.freedesktop.PolicyKit1.Authority.html#eggdbus-struct-Subject and http://lists.freedesktop.org/archives/polkit-devel/2009-December/000284.html.

I simply added ",'start-time':dbus.UInt64(0,variant_level=1)" as seen on the polkit-dev list to the polkit calls in is_authorized and obtain_authorization in gnome_lirc_properties/policykit.py to fix the error.

I am using PolicyKit 0.96.

This is a regression in PolicyKit, see bug:

Doesn't look like David wants to fix PolicyKit.

commit c3a6e62af251da0d38308612818a0811ffd04565

    Fix traceback on start with new PolicyKit
    
    From PolicyKit 0.95, the "start-time" portion of a unix-process
    became necessary, as PolicyKit checks for its presence when
    validating for arguments.
    
    We now pass a start-time of '0' so that gnome-lirc-properties
    doesn't traceback with a remote error, and the daemon checks
    for the start-time in /proc
