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:
In kde 3.5 the amarok user interface would freeze while trying to connect/stream some radio stations that weren't available/running.
In kde 4.3 the user interface is still responsive but the back end seems to be having the same problem.
When I chose a station that didn't work I could still choose another, and another... until suddenly the user interface would catch up very quickly (a timeout,  guess) but still no sound.
I didn't see a "buffering" progress display - is that gone in 4.3?

Anyway, when I closed amarok, the crash happened.
