Description

I found an existing report of this happening. ​http://lists.osgeo.org/pipermail/gdal-dev/2011-December/031154.html

For some reason, gdal2tiles is trying to fetch rows/columns of size 0 from the input dataset, which causes errors to be printed in ReadRaster(), but returns None data. The crash only happens in WriteRaster when data is passed in - it expects a string buffer but instead it get's the None returned by ReadRaster().

I have a fix, although I don't fully understand the root cause.

Attached is the patch file and image that causes the problem.

:> diff -w -u swig/python/scripts/gdal2tiles.py gdal2tiles.py > gdal2tiles.patch

No crash for me with GDAL 2.0-dev 32-bit, Python 2.7, on Windows 7.
