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.
