Description Cfossy3 2018-12-28 04:09:41 UTC 
Application: amarok (2.9.0)
KDE Platform Version: 4.14.38
Qt Version: 4.8.7
Operating System: Linux 4.15.0-43-generic x86_64
Distribution: Linux Mint 19 Tara

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to activate recent plugins to amarok, under linuxmint 19, when I received a message that there was no text program for KDE, therefore the console closed. Whenever I retsrated the program, it repeatedly closed with the same message.

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".

Unfortunately you do not have debugging symbols installed which are needed for a useful backtrace. Please install debugging symbols for Amarok and its dependencies and provide a new backtrace. See also https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

It would also be useful to know which exact plugins you tried to activate.
