                    hangs along with the plasma desktop widgets
           Product: dolphin
           Version: 19.08.1
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: ciaran.gillespie at gmail.com

  Target Milestone: ---

Application: dolphin (19.08.1)

Qt Version: 5.12.3
Frameworks Version: 5.62.0
Operating System: Linux 4.15.0-64-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed: I right clicked on a file to
open it in a text editor and when I right click Dolphin crashes

- Unusual behavior I noticed:
The plasma dock at the bottom of the screen all widgets on it become
unresponsive during this time as well

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
