-- Information about the crash:
- What I was doing when the application crashed:
booting up, if I was using Konqueror and it was still open at my previous shutdown or logout, then it crashes on restart or boot while trying to reload or recover last state, and I lose last state or session

The crash can be reproduced every time.

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