Unfortunately currently this does not work correctly for goemetryless
tables (the produced URI is malformed), therefore I advise you to
directly create URI string as mentioned in my earlier mail:
vlayer = QgsVectorLayer('dbname="/data/gis/test.sqlite"
table="mytable"', 'mytable', 'spatialite')

Here I would suggest to use directly tripProv->addFeatures( ... )
instead of using layer's addFeatures() method. This way you will
bypass layer's in-memory editing buffer and the operation will be
faster. I would like to explain the difference in the cookbook,
hopefully it will be added soon.
