dbus-daemon consumes 100% CPU

[Stuart Metcalfe]

Since installing Oneiric, I have seen my desktop randomly freeze for 1-2 seconds. Looking at top, dbus-daemon consuming 100% CPU coincides exactly with the freezes.

Status changed to 'Confirmed' because the bug affects multiple users.

Same for me. Funny though, the CPU-time consumption of dbus-daemon sometimes goes back to normal after a few minutes.

It seems to have something to do with evolution, for it is the one spamming the dbus.
My dbus-monitor gives thousands of messeges, similar to the following:

signal sender=:1.108 -> dest=(null destination) serial=237636 path=/org/gnome/evolution/dataserver/Calendar/2350/367; interface=org.gnome.evolution.dataserver.Calendar; member=opened
   array [
      string ""
      string ""
   ]
signal sender=:1.108 -> dest=(null destination) serial=237637 path=/org/gnome/evolution/dataserver/Calendar/2350/368; interface=org.gnome.evolution.dataserver.Calendar; member=opened
   array [

Oneiric has reached EOL since a while, and so is no more maintained.
