Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I have pointed Amarok to where my music collection is, and it started scanning it in the background. Meanwhile, I decided to inspect the list of radio streams. I clicked on the list to expand and Amarok crashed. I am using Ubuntu 9.10 64bit (GNOME) and I installed Amarok using Synaptic.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
