Application: kdeinit5 (5.0.97)

Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-gentoo x86_64
Distribution: "Gentoo Base System release 2.4.1"

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

I had just booted my desktop and logged in. The crash happend while my previous browsing session was restored.

The bug I marked as possible duplicate is remarkably similar to this though being from the kdelibs and qt4 era so not a true duplicate.

-- Backtrace:
Application: Konqueror (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
