Description Clarence Risher 2019-03-08 19:47:47 UTC

Application: amarok (2.9.70)

Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 5.0.0-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I had just compiled Amarok using the Arch Linux AUR package system, from https://aur.archlinux.org/packages/amarok/, and launched it from the .desktop file. The main window appeared, with the "local collections" settings window on top of it. In less than one second, with no further input except perhaps mouse movement, the program crashed.

Launching the program a second time shows the main window, and I can open the Settings window to select some folders for my local collection with no errors.

The crash does not seem to be reproducible.

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

Unfortunately a one-time crash is hard to solve, and your report has no debugging symbols. Since you use Arch, you need to compile Amarok and its dependencies with debugging enabled, else the backtraces are useless.
Closing this report as we can't use it.
