high CPU usage in certain apps

Hi,

for the past few days I'm experiencing weird CPU thrashing problems in two 
KDE apps: Amarok and Knode. Thought I would check if someone else is seeing 
this.

When playing MP3 files in Amarok, the X.org process hogs the CPU. It goes 
back to normal immediately if I stop the music. Details are in bug #557762.

Knode just started being very slow, taking several seconds to react to 
commands, while its CPU usage goes up. For example when selecting a 
newsgroup with a mouse click in the list, it takes seconds before even the 
selection changes (which usually happens immediately, before it startws 
loading new messages).

I don't know if these two are related but they both started happening in the 
last few days. I did upgrade Amarok recently but not KDE or Qt. I use amarok 
2.2.1-2, KDE 4.3.2 and th Qt 4.6 from experimental. System is a Thinkpad 
T61, Intel graphics, Debian amd64, mainline kernel 2.6.31.6.

Cheers,

Marcus
