-- Information about the crash:
- What I was doing when the application crashed:
When I close the last document with Ctrl+W I get a crash.

- Custom settings of the application:
It's with self-compiled Qt+KF5 with debug symbols and such. Maybe others haven't hit it because of it.

The crash can be reproduced every time.
