Application: amarok (2.8.0)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- What I was doing when the application crashed: Amarok crashes soon after mounting my Ipod classic 120GB. At first it seemed to work, then the first crash came after 10 - 15 minutes. After that it kept crashing within perhaps 1-2 minutes, before I even started working with it.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
