I load data in Marble Widget with "addGeoFataFile(kmlfile)" like the example "Loading KML" and removing them with "removeGeoData(kmlfile)".
When I load multiple kml data, I can remove the data only in LIFO order otherwise the app crash (access violation reading location by marblewidget-qt5.dll).
For example:
I load A.kml, B.kml, C.kml, and I can removing them only in this order: C.kml, B.kml, A.kml.

How can I solve this problem? Maybe I wrong to manage MarbleWidget data/layers?
