OSGeo vmap WMS tiles have artifacts

The layer is called "basic". wildintellect (on irc) has identified this as a collection rather than a simple layer.

Eastern Canada, one zoom level before artifacts become visible: ​http://www.pasteall.org/pic/47270 Eastern Canada on a subsequent zoom with artifacts: ​http://pasteall.org/pic/47271

wildintellect (on irc) has made a preliminary finding that inland_tile/inwater reprojection errors. Although he/she has not been able to find these artifacts in the original data (shapefiles). A sample screenshot from QGIS: ​http://www.pasteall.org/pic/show.php?id=47274

I have also seen some other (similar) artifacts when I have loaded up "​http://vmap0.tiles.osgeo.org/wms/vmap0" as a WMS layer in QGIS: ​http://pasteall.org/pic/47272

A small clarification to my above report:

While wildintellect's screenshot from QGIS shows the WMS layer with the artifacts, it also has some local layers.

update:

​http://vmap0.tiles.osgeo.org/wms/vmap0 ## works

​https://vmap0.tiles.osgeo.org/wms/vmap0 ## fails?

Do we still use that?
