Package: libgdal1-1.6.0
Version: 1.6.2-1
Severity: normal

*** Please type your report below this line ***
Apparently OGR's shapefile driver for reading polgyon rings and correctly
assigning them as inner, or outer rings and for which component of a
multipolygon for some complex polygon files is quite expensive. It may be
possible to define OGR_ORGANIZE_POLYGONS in the environment with the value
SKIP to avoid this work.
