Bug 394405

Application: kdeinit5 (18.04.1)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-41-generic x86_64
Distribution: KDE neon User Edition 5.12

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

– Right-clicked on trash and chose 'Empty Trash' from Dolphin's sidebar
– While the trash was being emptied, I navigated to the Home folder and refreshed it several times (for the purpose of checking available disk space)

Other conditions that might have contributed to the crash:

– While trash was being emptied, K4Dirstat was searching for files and folders in Home to list in its application window

-- Backtrace:
Application: Dolphin (kdeinit5), signal: Segmentation fault
