Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: i had amarok open, right clicked on my external drive on the left panel (external drive is a USB Seagate 1TB Hard Drive), and selected disconnect from collection.  Everytime i select this to stop the scanning of my external hard drive, the program crashes.

- Custom settings of the application:
- running amarok remote for android
- music library (120gb) is entirely contained on external hard drive

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
