            Bug ID: 382905
           Summary: Plasma crashes when I close chromium
           Product: plasmashell
           Version: 5.10.4
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: gregory.depie...@free.fr
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.9-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I quit chromium from Menu and it makes Plasma crash. I have regularly ten or
more windows open, each with a few tabs.
I'm not sure it happens all the time because often I reboot or stop Plasma
without quitting chromium first.

The crash can be reproduced sometimes.

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