Could you attach the backtrace rather than the core file? The core file does us no good without the binary that generated it.
(In reply to comment #3) > Could you attach the backtrace rather than the core file? The core file does > us no good without the binary that generated it. This only happens to me on g/fbsd - on ~ARCH amd64/x86/linux it works fine. Still want that backtrace?

Ah, my error on g/fbsd was that dbus wasn't actually running. How embarrassing for me :/ However, a better error message would be nice :)
Question for those of you seeing this: Are you sure there's a system bus? Is your user in the messagebus group? The only problem I can see in that code is a missing return in the error handling right before that function call. I can generate a patch that actually returns in the previous error case, if people are willing to try it.
gnome-screensaver works fine after I have added my user in messagebus group and started dbus service. It's unusually because it has worked fine before without these actions, and nobody know now what is necessary to do for using gnome-screensaver.
When you say it worked fine before, do you mean, it was working fine with gnome-screensaver 2.14 and stopped working with 2.16 ?
For me gnome-screensaver stopped working after upgrading DBUS to 1.0.
If you did revdep-rebuild and it stopped working with dbus-1 and gnome-2.14, I have no idea. when you moved to dbus-1.0, did you do revdep-rebuild, and did this bring along gnome 2.16 ? If this is the case, I'd say it is normal as gnome-2.16 requires dbus (for session bus) to work. Anyway has everybody here fixed his problem ?
The problem was that my user wasn't in messagebus group before and I didn't have dbus started. Now latest gnome-screensaver works fine with dbus. So bug can be closed.
Before we go closing this bug, can I please get a listing of the groups people are a member of? Messagebus should not be a group anyone belongs to, and with 2.16.3 gnome-screensaver works fine here - If dbus isn't started, there is no way that a program is going to connect to the message bus, it doesn't matter what group you are in.
groups: wheel audio cdrom video users portage messagebus I have removed my user from messagebus and it also works fine. So the problem was only in not started dbus service.
Closing as per comment #13 and #15. Thanks
