I have encountered a core dump while working with spatialite layers with latest master e052933b1452b5e45715c1a71f62be9d49ffe0d9

It is caused by trying to assign default field values in QgsSpatiaLiteProvider::loadFieldsAbstractInterface to the geometry column, which was skipped while creating fields.
Attached patch fixed this issue for me, but I am in no way familiar with the QGIS codebase so cannot guarantee this is the right approach.
