When I press the Spatial Query button QGIS crashes.

I think it's caused from having a non-spatial postgresql table in the map canvas.

I'm running PostgreSQL 9.6.6 and PostGIS 2.4.1.

Spatial Query will launch and work when there are just vector layers in the map canvas from the PG database.
But as soon as I add a non-spatial table from the PG database, Spatial Query crashes QGIS.

Here's the debug output when pressing the Spatial Query button.
