Ubuntu version : 13.04
Architecture   : x86_64
Problem in     : gnome-classic
dbus:
  Installed: 1.6.8-1ubuntu6
  Candidate: 1.6.8-1ubuntu6
  Version table:
 *** 1.6.8-1ubuntu6 0
        500 http://in.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
        100 /var/lib/dpkg/status

Frequent problems with dbus-daemon entering a runaway state, consuming 100% of one core for extended durations. KDE applications fail to open or react in a timely manner while this is happening. Couldn't open firefox, terminal, system monitor, vlc, gedit , etc...
Previously, I've been using 32 bit ubuntu with no problems (ever). This problem is there since I installed ubuntu 13.04.

Reproducible: Yes

Steps to Reproduce: Seems linked to login duration, running KDE apps (or
dbus enabled apps) include: Firefox, Network Manager.

Actual Results: One core at sustained 97(+)% cpu. dbus-daemon highest
process in "top" output. Killing dbus-daemon clears CPU utilization, but
then all KDE and dbus applications(like firefox, nautilus, network
manager applet)  fail to run until restart.

Expected Results: dbus-daemon should not runaway.

ps -ef output for dbus-daemon process:
