            Bug ID: 421488
           Summary: Plasma crashes after login
           Product: plasmashell
           Version: 5.18.5
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: ro...@xtra.co.nz
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.18.5)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 4.12.14-lp151.28.48-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed: On login, KDE desktop opened
with default wallpaper and icons repositioned.  While restoring custom config,
desktop crashed to blank (black) and unresponsive screen 

- Unusual behavior I noticed:  Several reboots all resulted in similar
behaviour, ending with Plasma crash and black screen

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
