Package: plasma-desktop Version: 4:5.8.4-1 Severity: grave --- Please enter the report below this line. ---
Dear Maintainer, When using plasma-desktop without upower installed on the system, plasma-desktop segfaults when I disable a screen with kscreen. Steps to reproduce the bug: + You will need two screens connected to the system to be able to reproduce this bug. 1. Make sure upower is not installed on the system. 2. Go to kscreen configuration module. 3. Disable one of the two screens and apply settings. You will see that after disabling a screen, plasma-desktop segfaults. Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
