QGIS Crashes frequently when I try to delete something from a duplicated map layout.

[boonits]

What is the bug or the crash?

User Feedback

This happens frequently. When I duplicate a map, and then try to delete anything from the copy (i.e., a polyline, some text), it's a coin toss if it crashes or not.

2. duplicate the print layout
3. in the opened duplicated layout zoom in ( ! )
4. click on the textfield with the content "DELETE ME" and delete it
5. QGIS crashes
