Exporting Shapefile to SpatiaLite format using QGIS?

I am trying to export a shapefile of 3221 mixed POLYGON and MULTIPOLYGON geometry elements and every time, I get this same error:

Does anyone have any idea what's going on?

And no, this is not an exact duplicate of https://stackoverflow.com/questions/15203403 as I am working solely within QGIS.
