[root at osprey ~]# rpm -q dbus gdm gnome-vfs2-devel

Running gdmsetup under current rawhide (current except for elfutils)
results in the following error messages, and the application itself is
unresponsive and reports 90+% cpu usage until manually killed.

[root at osprey ~]# gdmsetup

(gdmsetup:3244): libgnomevfs-WARNING **: Failed to open session DBUS
connection: Unable to determine the address of the message bus (try 'man
dbus-launch' and 'man dbus-daemon' for help)
Volume monitoring will not work.

incorrect, assertion "connection != NULL" failed in file

This is normally a bug in some application using the D-BUS library.
