Hi,

I'm trying to create an image from a Geopackage with MapServer. 
I can recreate the issue using data from http://www.geopackage.org/#sampledata

It appears a v1.1 Geopackage will throw an error if the Sqlite database does 
not include the Spatialite extension. 
A v1.2 Geopackage does not seem to produce the same error. 
Even's patch fixes this error. It also seems the issue disappears when using a 
dev 2.3.0 build of GDAL. 

A sample Mapfile using the sample datasets is below. The first shp2img command 
works, the second does not. 

shp2img -m test.map -l point2d_v1_2 -o test.png
shp2img -m test.map -l point2d_v1_1 -o test.png    


MAP
    # cd /D C:\MapServer\apps\gpkg
    # shp2img -m test.map -l point2d_v1_2 -o test.png
    # shp2img -m test.map -l point2d_v1_1 -o test.png    
    SIZE 200 200
