This is probably the same issue as bug 390011, but that one’s closed and didn’t name the right package for the issue either. sys-apps/dbus-1.4.16-r2, with the supplied init script, puts machine-id in /etc. It used to be in /var/lib/dbus. glib-2.30.1/gio/gdbusprivate.c has the latter path hard-coded. $ ls -l /etc/machine-id -rw-r--r-- 1 root root 33 Nov 1 13:22 /etc/machine-id $ ls -l /var/lib/dbus/machine-id ls: cannot access /var/lib/dbus/machine-id: No such file or directory When starting evince, it complains to stderr about the missing machine-id: Failed to get bus connection: Cannot spawn a message bus without a machine-id: Unable to load /var/lib/dbus/machine-id: Failed to open file '/var/lib/dbus/machine-id': No such file or directory If there was no PDF file given on the command line, it also prints: GConf Error: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Cannot spawn a message bus without a machine-id: Unable to load /var/lib/dbus/machine-id: Failed to open file '/var/lib/dbus/machine-id': No such file or directory) If no PDF file was given, an empty evince window comes up, but attempting to load a file does nothing (after selecting one from the file choosing window). If a PDF file was given, no window comes up and evince hangs. (I didn’t get a meaningful backtrace or ltrace for this yet.) It works fine if glib is recompiled with the path changed to /etc/machine-id. I have no idea of what’s going on inside evince that depends on this, but, hey, the path in glib might as well be correct. So the following patch is helpful with a recent dbus version. (Note: probably counter-productive with *old* dbus, before whenever the machine-id path changed.) Custom USE flags in addition to the emerge --info output: -doc for glib (owing to bug 387385), nothing for evince or dbus. Reproducible: Always Steps to Reproduce: 1. evince blankpdf.pdf # (Or any other PDF file.) Actual Results: Errors on stderr, no evince window, evince process keeps running. Expected Results: Show the PDF file. $ emerge --info Portage 2.1.10.33 (default/linux/amd64/10.0, gcc-4.5.3, glibc-2.13-r4, 3.0.7-tuxonice x86_64)

Created attachment 292171 [details] Hardcode /etc/machine-id instead of /var/lib/dbus/machine-id in glib. This fixes this issue for me, but it’d break things for people whose dbus init script puts machine-id in /var/lib/dbus.
Can confirm that - firefox complains about the missins /var/lib/dbus/machine-id file. As a workaround, you can run this command: sudo dbus-uuidgen --ensure=/var/lib/dbus/machine-id Would be nice if this bug is corrected asap, it's a bit lame having applications complaining about that (some don't even start, as "revelation" password manager - you can imagine the mess while using it at office....) Thank you. cheers, C.
Should be set in tree with glib-2.30.1-r2 and proper blockers in place to enforce this.
