Application that crashed: amarok
Version of the application: 2.1.80
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I had just opened Amarok, and wanted to browse my collection, which (oddly) wasn't already open.  So I clicked on it, maybe a couple of times; it didn't seem to respond immediately.  But a second or two later, it crashed without opening the collection at all.

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