Bug 402966

Application: kwrite (18.12.0)
 (Compiled from sources)
Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.13-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to save a new and empty file. I wanted to save it in a new directory. Creating the directory lead to kwrite crashing.

-- Backtrace:
Application: KWrite (kwrite), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
