Application: amarok (2.4-GIT)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic-pae i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I type an artist name and get the corresponding artist in my local collection.
After few seconds, I select the searched text and type another artist name. I see that the new name I type replace the previous one, that the collection treeview began to change while I'm still typing, then amarok crash.
It's often appen on my ubuntu lynx computer and I dont remember having seen this bug on my mandriva one.

the last lines show on the console when launching amarok --debug where:
