[Bug 1755040] [NEW] amarok crashes when mouse leaves window

Sun Mar 11 22:54:16 UTC 2018

Public bug reported:

Application: amarok (2.8.0)
KDE Platform Version: 4.14.34
Qt Version: 4.8.7
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 17.10

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

I have a dual monitor setup.  When Amarok is in full screen on one
monitor and when mouse moves to the other monitor amarok crashes every
time.  This behavior started after performing an apt dist-upgrade which
upgraded plasma packages to 4:5.12.3-0ubuntu1~ubuntu17.10~ppa1

The crash can be reproduced every time.

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