Clashes on Ubuntu when saving a file

Hi. It was working fine on Manjaro OS. It clashes when I save a text file on Ubuntu 19.10.
```
qml: edit page completed
saved to "/home/edip/workspace/deneme/d2"
QUrl("file:///home/edip/workspace/deneme/d2") "/home/edip/workspace/deneme/d2"
Segmentation fault (core dumped)
```

Reproduce the crash by saving a text file on Ubuntu 19.10, using the reported QML output and file path as the starting point. Trace the save path to identify where the segmentation fault occurs, then verify that saving completes without a crash on Ubuntu while preserving the existing behavior on Manjaro.
