Can I recall that email?  The link points where it should.

I can see a few problems in the output.  First is that rather than trying
to open /home/rick/build/subsurface/build/marbledata/bitmaps/xxx it's
trying to open /bitmaps/xxx

Next, it's trying to open kml files in the placemarks directory, which
doesn't exist.

And thirdly, it's trying to open bitmap files that don't exist.

Full output is:

fullpath /bitmaps/default_location.png results in
fullpath /bitmaps/empty.png results in
fullpath /maps/earth/srtm2/srtm2.dgml results in
Map theme file does not exist: ""
