Title:
  compiz crashed with SIGSEGV in dbus_connection_dispatch()

Status in compiz package in Ubuntu:
  Invalid

Bug description:
  playing around in ccsm, after I noticed that it was continuously
  consuming 15-20% processor time. At some point I enabled the DBus
  Control Backend, which went alright. Subsequently I enabled or
  disabled one of the application switchers, which caused compiz to
  restart, which is apparently when the DBus problem occurred.
