App crashes after clicking a photo and rotating the screen immediately

Expected behavior

The app must be stable on screen rotation after capturing a photo.

Actual behavior

But the app crashes when I capture a photo in landscape mode and rotate the screen to potrait mode immediately after clicking OK.

How to reproduce

1. Install the app from Fdroid.
   
2. Launch the app.
   
3. Click on the camera icon on top right corner of the app and click a photo in landscape mode (only go to landdcape mode in camera). (With autorotation enabled)
   
   After clicking the picture clicking OK in landscape mode.
   
4. Now right after clicking the picture rotate the screen to potrait mode.
   
   The app crashes.
