Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.9-1-ARCH x86_64
Distribution: "Arch Linux"

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

I was listening to a Cool Stream (FREQUENCE3)
which was broadcast to my Pioneer VSX-1022 via pulseaudio-raop2

but i don't think these element are related, I am just mentioning for sake of completeness

Running ArchLinux rolling release. everything is up to date Plasma 5.10
except for pulseaudio, I am still on 7.1

going into Amarok settings

enabled 
* automatically retrieve cover art
* enable context applets collapse animations
* show background images in the browser panel
* show moodbar in progress slider

clicked apply, instant SegV... no stacktrace

restart amarok,

disabled
* show moodbar....

clicked apply, instant SegV... no stacktrace

restart amarok,

disabled
* automatically retrieve cover art
* enable context applets collapse animations
* show background images in the browser panel

clicked apply, instant SegV... stacktrace attached

The crash can be reproduced every time.

-- Backtrace:

Your backtrace has no debugging symbols, you need to recompile Amarok and it's dependencies with debugging enabled to get a meaningful backtrace.

Comment 2 Mathieu Jobin 2017-08-14 16:11:24 UTC

I a having issues compiling latest amarok from git using KF 5.36

$ pacman -Q kdewebkit
kdewebkit 5.36.0-1

first had issues finding /usr/include/KF5/KDEWebKit/kgraphicswebview.h

I updated the include statement, and now it having issues around keyword Q_DECL_OVERRIDE

i don't know if its Amarok or kdewebkit that needs updating

my system is all up to date, Plasma 5.10.4, Framework 5.36 and Qt 5.9.1

thanks

I suggest you talk to your distribution, as they are apparently capable of compiling it, sadly they do not provide debugging symbols.
