Description Marco Cilloni 2018-03-17 10:20:21 UTC

Application: plasmashell (5.12.3)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.8-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to select a window of an application running under XWayland (vscode). Both a simple menu and the full preview menu (which does not work yet) appeared; after clicking on one of the two (I cannot easily replicate this) a segfault ensued.
- Custom settings of the application:
I'm using the icons only task manager.

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