Amarok constantly consumes 20% CPU even when doing nothing (Karmic)

[Atul]

Binary package hint: amarok

After using Amarok for a while on brand new install of Kubuntu 9.10, noticed that it is consuming around 20% CPU even when (apparently) not doing anything (see attached snapshot). This can't be doing any good for my laptop's battery life.

Regards,

I can confirm this bug, including roughly the same percentage.
(top indicates 20% process use, on an Intel X60 with Core 2 Duo)

The process goes to 0% CPU when "Stop playing song".

Sometimes, it uses a very reasonable 1..2% CPU.

The excessive CPU use has also been seen when a song is paused.

I can not reproduce the problem at the same severity when the playlist contains only a few songs.
So there may be a relation with my bug https://bugs.launchpad.net/ubuntu/+source/amarok/+bug/474059

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
