To #11 Nicholas, I tried the solution Reuben proposed in #10 and
installed the dbus trusty packages on Ubuntu 13.10 saucy. Since then,
the problem with high CPU load has not appeared again (about a week
now). So it seems to work.

In particular, I installed the following:
dbus_1.6.18-0ubuntu3_amd64.deb
dbus-1-dbg_1.6.18-0ubuntu3_amd64.deb
dbus-1-doc_1.6.18-0ubuntu3_all.deb
dbus-x11_1.6.18-0ubuntu3_amd64.deb
libdbus-1-3_1.6.18-0ubuntu3_amd64.deb
libdbus-1-3_1.6.18-0ubuntu3_i386.deb
libdbus-1-dev_1.6.18-0ubuntu3_amd64.deb

  dbus-daemon consumes 100% cpu without reason

Status in “dbus” package in Ubuntu:
  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.
