Application: amarok (2.4.3)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: While Amarok was opened. I mounted my Motorola Droid 2, went in via Dolphin, and cleared my Music folder. I noticed that in Amarok, my tracks were not showing up, but the count was the same. I put new songs on my phone via Amarok, by making a playlist then dragging it over to my phone's collection. The songs copied successfully. I clicked the eject button next to my phone's collection, and Amarok crashed. I usually use the Device Notifier to unmount my phone.

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