Application: dolphin (17.12.2)

Qt Version: 5.9.3
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed: Today Dolphin crashed twice. Once when the system was booting (no debug info included about that here) and the other occassion was when trying to select a folder in the folder panel. Nothing else was done.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Illegal instruction
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
