QGIS » QGIS Application

QGIS crashes when opening and closing the layer properties window of a non-geometry layer such as a csv dataset. It has to do with the style dock's undo stack.

1. Create a new project
2. Add a non-geometry dataset (csv, xlsx, etc.)
3. Open the layer's properties window
4. Close the properties window by clicking on the [ OK ] button
5. boom QGIS dies
