I feel that this dbus-launch behavior is worth sending new bug.

I'm reassigning this to glib2. glib2 launches the dbus-launch and should probably require the dbus-x11 package.
The problem with initialization of X11 belongs to glib2 too probably since I don't see it if running dbus-launch without the "--autolaunch" option (I'm not sure whether it could be detected when dbus-launch needs it and when it doesn't).

Regards

After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
