If a user starts evolution and there is not a dbus-daemon dbus-launcher it just crashes at startup.

evolution

Or if you start a graphical session that does not launch dbus-daemon for example xinit + twm

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
1.Start a session that does not launch dbus-daemon or kill user's dbus-daemon
2.
