Package: dbus-x11 Version: 1.4.16-1 Severity: wishlist Usertags: pca.it-virtualization
Hi there! I am trying to setup Empathy in a schroot and found out that it is quite difficult to get all the D-Bus stuff to work together [1][2][3][4]. Moreover, I could not find a complete guide about what is needed: thus, I am here to understand the correct procedures to then write an entry for README.Debian. [1] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599518#15> [2] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=619636#70> [3] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649744> [4] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649884> First of all, here what my /etc/schroot/desktop/fstab [1] contains: --8<---------------cut here---------------start------------->8--- ## D-Bus support /run/dbus /run/dbus none rw,bind 0 0 /var/lib/dbus /var/lib/dbus none ro,bind 0 0 ## PulseAudio device discovery support ### <http://bugs.debian.org/649884> /run/udev /run/udev none rw,bind 0 0 --8<---------------cut here---------------end--------------->8--- [5] However, I found two major problems, which are maybe correlated: 1) D-Bus services not provided by any .service files ===== luca@gismo:~$ schroot -c sid-desktop (sid-desktop)luca@gismo:~$ epiphany Gkr-Message: secret service operation failed: \ The name org.freedesktop.secrets was not provided by any .service files (sid-desktop)luca@gismo:~$ empathy ** (empathy:21365): WARNING **: _nm_object_get_property: \ Error getting 'WirelessHardwareEnabled' for /org/freedesktop/NetworkManager: \ (9) Rejected send message, 2 matched rules; type="method_call", \ sender=":1.29" (uid=1000 pid=21365 comm="empathy ") \ interface="org.freedesktop.DBus.Properties" member="Get" error name="(unset)" \ requested_reply="0" destination="org.freedesktop.NetworkManager" \ (uid=0 pid=1691 comm="/usr/sbin/NetworkManager ") ** (empathy:21365): WARNING **: _nm_object_get_property: \ Error getting 'WwanHardwareEnabled' for [same as above] ** (empathy:21365): WARNING **: _nm_object_get_property: \ Error getting 'WimaxHardwareEnabled' for [same as above] ** (empathy:21365): WARNING **: _nm_object_get_property: \ Error getting 'State' for [same as above] ** (empathy:21365): WARNING **: _nm_object_get_property: \ Error getting 'State' for [same as above] (empathy:21365): folks-DEBUG: individual-aggregator.vala:305: Setting primary store IDs to defaults.

(empathy:21365): libnotify-WARNING **: Failed to connect to proxy (empathy:21365): folks-WARNING **: Error preparing Backend 'telepathy': \ The name org.freedesktop.Telepathy.AccountManager was not provided by any .service files (sid-desktop)luca@gismo:~ ===== If I have understood correctly, this is because *outside* the chroot D-Bus could not find .service files in /usr/share/dbus-1/services/. This is normal, given that the packages shipping these files are not installed *outside* the chroot. These problems go away if I clear DBUS_SESSION_BUS_ADDRESS before starting the applications above. This is done automatically adding the 'environment-filter=DBUS' to the corresponding stanza in /etc/schroot/schroot.conf. 2) even after having cleared DBUS_SESSION_BUS_ADDRESS, however, empathy gave the same error about the 'telepathy' backend. The solution seems to indeed clear DBUS_SESSION_BUS_ADDRESS, but only if /var/lib/dbus/machine-id contains a value different than the one *outside* the chroot. This is done not bind-mounting /var/lib/dbus in the chroot, something which is in contrast with what Steve McIntyre (Cc:ed) reported about one year ago for PulseAudio [5]. Please note that I have already reported that bind-mounting /var/lib/dbus or not makes no difference for me to have PulseAudio working in a chroot [4]. Is this a bug in empathy?
