no content, no error ...

[a2800276]

... further along in my trials of kartograph, I tried the "ne_50m_admin_0_countries" example with a file of my own that I am interested in:

 http://www.offenedaten-koeln.de/offene-daten/?did=48

which also contains POLYGONs as the ne_50m... shapefile. I only changed the 'src' attribute in the configuration JSON. Output is an svg containing only metadata, but no error or indication why the actual shapes are not in the file... :
