Sentry Crash Report:

Description Andreas Hurka 2019-03-09 22:13:05 UTC 
Application: amarok (2.9.0)
KDE Platform Version: 4.14.38 (Compiled from sources)
Qt Version: 4.8.7
Operating System: Linux 4.15.0-46-generic x86_64
Distribution: KDE neon User Edition 5.15

-- Information about the crash:
- What I was doing when the application crashed:

I had restarted my PC and wanted to hear some musik. I started amarok to do so. Every single track (apart from the amarok theme) was light grey marked, as usual when I restart the PC. That may be because of the fact that all my musik is on an external drive which has to "boot"? up to access to data.
In the session before I did some changes in amarok (see custom settings) so amarok tried to import the musik I guess. I looked in the amarok media browser (on the left side) and saw that the medium wasn't mounted. So I went in dolphin and opened it.
After that amarok showed me a very long list of duplicates and crashed.
After restarting it everythink works fine.
The crash reporting assistant asked me to install debugging icons. I did so.

- Custom settings of the application:

added /media to local collection (Is it called that way or library?)
added the external USB drive "My book" to the statistics matching
checked continue playing after start (or is that default?)
set amarok to shuffle mode (may not be related)

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

The crash was not caused by Amarok, but by the IO system. You should always mount the media before starting Amarok to avoid this, else it could cause conflicts with the already mounted sources.

FWIW: please install debugging symbols for all dependencies of Amarok, e.g. pulseaudio as this might hide some necessary information in a backtrace.
