            Bug ID: 367574
           Summary: Plasma Crashed after a system restart and a winow move
           Product: plasmashell
           Version: 5.5.5
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: burden.p...@gmail.com
                CC: bhus...@gmail.com, plasma-b...@kde.org

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-34-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: I had just rebooted my system
because of an earlier crash in handbrake and not being able to start
applications after that crash. After the reboot I moved a konsole window, that
I have started at boot time, from one screen to another and started nmon in it.
That was the only window I was able to get a keyboard response from at that
point.

- Unusual behavior I noticed: Although the mouse was moving I couldn't get a
response from any application or the K-Start button to do anything. The only
response I could get was inside the konsole window. I do have a lvm volume that
is syncing after the reboot but that was the only significant system activity I
could see in the nmon display.

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