Description

In new QGIS work session I added new vector layer (shapefile) with single point and QGIS showed me nothing. I clicked "Zoom to layer" and still nothing, "Zoom full", "Zoom to selection" and still nothing. Then I added other vector layer with more data, clicked "Zoom to layer" on second layer and then both layers where displayed correctly. Still "Zoom to layer" was not working correctly for layer with single data point.
