[Pkg-utopia-maintainers] Bug#591618: consolekit not started automatically when logging in with kdm

[Martin Steigerwald]

Package: consolekit
Version: 0.4.1-4
Severity: important

I recently upgraded my Dell workstation at work from Lenny to Squeeze.

Upon logging in with kdm 4:4.4.5-1 I get the following error dialog:

"Warning: Cannot open Consolekit session: Unable to open session:
Failed to execute programm /usr/lib/dbus-1.0/dbus-daemon-launch-helper:
Success"

This happens on every login not only on the first one (see 
http://bugs.debian.org/562026). Also that launch helper is setuid root
(see http://bugs.debian.org/578203 and http://bugs.debian.org/569058):

ms at mango:~> ls -l /usr/lib/dbus-1.0/dbus-daemon-launch-helper
-rwsr-xr-- 1 root messagebus 39880 27. Jul 21:39 /usr/lib/dbus-1.0/dbus-daemon-launch-helper

I have the following in syslog:

Aug  4 09:22:59 mango kdm: :0[21127]: Cannot open ConsoleKit session: Unable to open session: Failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success
Aug  4 09:23:01 mango ck-launch-session: error connecting to ConsoleKit

When I click "Ok" in the dialog, I still can login, but after some time I can
not lock the KDE session anymore, also Alt-F2 for running KRunner does not work.
When I logout and login again both functions work again.

When trying again with pressing Ctrl Alt Backspace when I see the
error dialog:

Aug  4 10:08:43 mango kdm: :0[10486]: Cannot open ConsoleKit session: Unable to open session: Failed to execute program /usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success
Aug  4 10:08:47 mango kdm: :0[10486]: Cannot read from greeter for display :0
Aug  4 10:08:47 mango kdm: :0[10486]: Abnormal termination of greeter for display :0, code 1, signal 0
Aug  4 10:08:47 mango kdm: :0[10486]: Cannot close ConsoleKit session: Unable to close session: no session open

There is no console-kit-daemon process running.

To work around this issue I just started consolekit-daemon as root manually.
Then I didn't get an error message at boot.

I do have an Debian Squeeze/Sid/Experimental setup on my ThinkPad T42 setup
with same versions of ConsoleKit, DBUS and KDE, where this problem does
not happen. The only notable difference I can think of is that the
workstation as /home mounted via NFS while the ThinkPad has it as Ext4
filesystem. / is on an Ext4 filesystem is both cases. The NFS export is
mounted with root_squash, so that root cannot access it:

mango:~# LANG=C touch /home/ms/testfile
touch: cannot touch `/home/ms/testfile': Permission denied
