Sentry Crash Report:

Description szmaszmo 2018-03-08 19:20:29 UTC 
Application: kdeinit5 (5.0.97)

Qt Version: 5.9.2
Frameworks Version: 5.42.0
Operating System: Linux 4.14.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:
I have just logged in to KDE session.
From the backtrace it looks like, KDE browser (Konqueror) crashed by fetching/getting/reading url (was it empty? invalid? null?).
Actually I have no idea, why the browser was started right after login.
I was not using it before almost at all.

-- Backtrace:
Application: Konqueror (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
