[Bug 1230031] Re: dbus-daemon consumes 100% cpu without reason

 

I've been running Ubuntu 12.04 (with various de's over time) for two
years and saw this error happen for the first time today.  I'm currently
running Gnome Shell 3.4.1, but I haven't removed Unity.  My Xubuntu
12.04 with xfce 4.8 has not shown this behaviour to date.

  Confirmed

  Just login in to session, and dbus-daemon consumes 100% of cpu.
  Before, I did a login and logout. This problem appears randomly, not
  all the time.
