Comment 6 for bug 193578

I can confirm that. To reproduce:
1.Open in Firefox long page like: https://launchpad.net/ubuntu/+milestone/ubuntu-8.04
2.Play in Rhythmbox internet radio station like: http://www.sky.fm/aacplus/smoothjazz.pls
3.Scroll page in Firefox _with mouse wheel_, not with slider.
I have System Monitor on upper panel.
When scrolling page consuming 100% CPU then Rhythmbox stop playing and not playing back.
With local mp3 file sound interrupt for a while only.
Very sorry for my English.

Fully updated Hardy Beta.
