            Bug ID: 419896
           Summary: Dolphin crashes when terminal panel is left on.
           Product: dolphin
           Version: 19.12.3
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: burdebc at yahoo.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (19.12.3)

Qt Version: 5.14.2
Frameworks Version: 5.68.0
Operating System: Linux 5.6.3-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Recently I have noticed that Dolphin would crash almost immediately when I
opened it.  Today I noticed that Dolphin would sometimes hang for a few seconds
while showing a blank terminal panel.  I then disabled neofetch thinking that
the terminal was having trouble loading neofetch, but the crashes continued.  I
also disabled powerline shell in my .bashrc, but that did not help either.

- Unusual behavior I noticed:
Dolphin would crash almost immediately after launching.  Dolphin would launch
normally on the second or third attempt to relaunch it.  After disabling
neofetch and powerline shell in my .bashrc I noticed that Dolphin would work
normally every time after turning off the terminal panel

- Custom settings of the application:
Terminal panel enabled, Powerline shell and Neofetch enabled in .bashrc

The crash can be reproduced every time.

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