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
