I was doing correction of topology errors.

Debug: /home/ale/dev/cpp/qgis/src/app/qgsmaptoolvertexedit.cpp: 440: (canvasReleaseEvent) [[DeleteVertex]].
Debug: /home/ale/dev/cpp/qgis/src/core/qgsgeometryvertexindex.cpp: 58: (back) mIndex contains: 3640

Program received signal SIGSEGV, Segmentation fault.
