Description

Having a very recent master version of QGIS: 4c4e8ac18a

Only having one (valid) project in the Recent project welcome screen.

Removing that one project (immidiatly after opening QGIS) QGIS crashes.

Looks like #18118

But not sure if it is the same.

This is the stacktrace:

History

#1 Updated by Richard Duivenvoorde over 2 years ago

  • Crashes QGIS or corrupts data changed from No to Yes

Easy reproducible even in fresh profile:

- create fresh profile
- open osm layer
- make this (unsaved) project your default project (Settings/general)
- now save the project
- close qgis
- open qgis
- seeing the osm project as only project, delete it from the list in welcome page
- not sure if needed, but move your mouse of canvas/layerlist/browser
