Application: dolphin (18.12.2)
 (Compiled from sources)
Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 4.20.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

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

With dolphin-plugins-git installed and enabled,
with dolphin navigated inside a git repository (digikam.git top dir),
activating 'Split View' via toolbar,
then immediately hitting 'Close' (Split View) again,
dolphin crashed.

The crash does not seem to be reproducible.

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