Steps to reproduce:
1. Construct and place burner radar.
2. Left-click radar entity to open entity GUI.
3. Insert fuel into the radar entity.
4. Factorio immediately hangs for several seconds, then crashes.
Correction: Factorio will crash, no matter how fuel is inserted into the radar, as long as the radar GUI is open when fuel is inserted.
Error StatusWidget.cpp:31: Entity radar of type radar at position {4.5000000000, 1.5000000000} has status None
