On a different machine I just had the same issue. That one is a quad 
core i5. dbus-daemon was using 100% cpu cycles on one of the cores. But 
no un-running programs would start, i.e. Thunderbird, or even a konsole 
window. I closed those windows that were running and dbus-daemon stopped 
immediately after I closed a Dolphin window (opened to Home). Now it 
gets a little more interesting. A short while after that, say about 30 
seconds or so, dbus-daemon started taking up 100% cpu on a different 
core. Still no programs would open, so I switched to console 1 
(ctl-alt-F1) and ran dbus-monitor. That reported that dbus-daemon did 
not start correctly giving an error X11 dbus-daemon failed to load. But 
top showed it utilizing 100% cpu. (BTW this machine is also running 
openSuse 11.4 with KDE).

Would appreciate any ideas. Thanks.
