So where is the problem

First of all: we need to know what version of Amarok you are using, and what Phonon backend (settings > configure Amarok > playback > configure Phonon > backend). The current version of Amarok is 2.4.3; if you are using an older version there's a fair chance that the issue has since been fixed.

The console output provided is not useful for debugging; we need crash traces. Dr Konqi should pop up when Amarok crashes; follow instructions on the developer information tab there to install debugging symbols and get a backtrace.

Sorry i forgot to give more info... i'm using ubuntu natty with kde 4.7 with nvidia current, my amarok is 2.4.3 and in "configure amarok/playback/configure phonon/backend" it's says i'm using gstreamer "Phonon Gstreaner backend" 4.5.0
When amarok crash and kde crash handler pop's up in "developer information" tab i get this:

Code: Select all

And btw thank you for your fast respond

Please do NOT post bug or crash reports here but file a bug in http://bugs.kde.org. The forum is the wrong place for that, we do NOT handle bug reports here, see also viewtopic.php?f=115&t=67238

I have the same problem here. Yesterday I did a fresh install of Kubuntu 11.10 Beta with
Amarok 2.4.3.
A. Crashes everytime after starting a song, from collection or filebrowser.

Phonon: VLC-backend or Gstreamer-Backend: neither worked.

This is related to a bug in QtWebKit4, please ask your distribution to provide the upstream patches available. See also https://bugs.kde.org/show_bug.cgi?id=279813, comment #46

Today's update did it for me. Thanks
