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:
I am editing a snapcraft description file under a source tree managed by Git, I decided to created a orphan branch and commit it in there instead so I run a git checkout --orphan <branchname> and run `git rm --cached *` to unstage all existing files and `git clean -dfx` to remove all untracted files

- Expected Behavior: 
The files are removed, Dolphin and Kate run normally with a prompt of the directory/file browsing is deleted

- Current Behavior:
Both application crashes, no backup :-(

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