Application: dolphin (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-45-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Was about to move files from one folder to another in split view mode. Accidentally hovered over the dropdown folder menu (breadcrumb ??) and made it show all the subfolders. It partially covered the folder I was about to move the files to. With all the files still selected, moved away from the dropdown(it did not dissapear), tried to hover over the folder but hovered over the dropdown instead, moved the mouse away, and carefully hovered only over the folder. Let go of the mouse button and used the mouse to select the ' Move Here' option. Then Dolphin crashed.

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