It is the same with 2.76 version.

And I experienced it on meshes imported with SHP importer: https://github.com/domlysz/BlenderGIS

There I filled another bug, don't know if it is related to this issue. Maybe SHP importer produces somewhat corrupted meshes? Blender shouldn't crash on them anyways, it should report some error ...

Importers that don't ensure correct mesh data need to run validate(),
https://www.blender.org/api/blender_python_api_current/bpy.types.Mesh.html#bpy.types.Mesh.validate

This should be fixed in the add-on.

For a quick workaround exit edit-mode and run this in the Python console: C.object.data.validate()
