Crash when changing datasource

[jmacura]

User Feedback

I was changing a datasource for one layer for which I moved the source (GeoTIFF file) into another directory.
It took some time loading it, so I left QGIS running but switched my focus to a browser window for some time. After several minutes I wanted to check if the layer already reloaded the datasource, but instead I have seen this pretty crash window...

Just tested the same with empty user profile. Crashed again (I didn't even left QGIS as previously, just let it running in the front) after some 20 seconds.

I was changing a datasource for one layer for which I moved the source (GeoTIFF file) into another directory.

@jmacura can you describe in detail the steps to replicate? thanks.

[jmacura]

@gioman sure!

Steps to reproduce

1. Open new project
2. Load GeoTIFF as a new raster layer
3. Save project
4. Quit QGIS
5. Go to your file system, move the .tiff file somewhere else
6. Open QGIS and reopen the project
7. The .tiff file won't be found (logically), hence the prompt dialog appears
   
8. In the prompt select option "Keep Unavailable Layers"
9. Right click on the layer, choose "Change Data Source...." (it's in Czech in the image as it's a default language in an empty profile)
   
10. Find the new location of the file, click "OK", wait for the crash to happen

Is this sufficient? I can attach testing .qgz and testing .tiff files if needed.

[jmacura]

And one more comment:
In step no. 7, if I choose "Browse" in the prompt dialog and relink the file from there, it works just fine.

Confirmed also here.
