            Bug ID: 375456
           Summary: [wayland] Plasmashell NVIDIA+nouveau crashes when
                    using application launchers.
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: jodr666 at live.com
  Target Milestone: ---

Application: plasmashell (5.9.90)

Qt Version: 5.7.0
Frameworks Version: 5.31.0
Operating System: Linux 4.9.5-040905-lowlatency x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on  "Application Dashboard"

- Custom settings of the application:
I set "LIBGL_ALWAYS_SOFTWARE=1"

Had a while since i tried/tested wayland seasion due to my deskop locking when
i do the same without setting the aformentioned variable. As far i now the
variable stop "acceleration" which explains the performance hit on the desktop.

NVIDIA+nouveau still a no go on wayland sadly.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
