I'm not sure exactly what caused it, but I noticed the same thing on one of my machines. It turns out I no longer needed the package that had brought qpid along with it anyway (Matahari), but the problem was exactly what you describe. On another note, however, Firefox now completely consumes one processor's time any time it is started, even with scripting and all plugins removed. This is worse than the qpid problem because Firefox isn't set to a lower priority level, so it is really noticeable on lower-power systems with only one or two processors. Thunderbird also now chews up a lot of CPU time, but it is intermittent, not constant the way Firefox is.
