Operating System: Linux 4.13.0-38-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed: Nothing. This issue started this morning after coming out of sleep, but continues to happen even after a fresh reboot. No new software, other than updates, have been installed. Every time I open Dolphin i see it open briefly then immediately close.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
