[mapserver-users] MapServer and Geopackage failing

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
