Description Mickaël 2011-05-01 13:24:30 UTC

Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
My external USB harddrive was connected but I recently unchecked the "Automatically enable when connected" box (before Amarok's start) and I clicked on the green checked box in order to enable it. And then crash.
I am using the last GIT version (compiled yesterday).

The crash can be reproduced some of the time.

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