[gdal-dev] BuildOverviews (python) going nuts?

[Vincent Schut]

Hi folks,

is it just me, or is the BuildOverviews function behaving strange on you to?
I regularly call someDs.BuildOverviews("AVERAGE", [plist]) on my output 
datasets (in swig python, that is). Until some time ago (can't tell 
precisely, have been out of business for some time) this worked find. 
However, currently I get the following errors:

ERROR 1: TIFFSetField:/home/mrp/modis/zandbak/vzaCorrectionTest.tif:

ERROR 1: GTIFFWriteDirectory:Can not write tiles to a stripped image

Which is quite strange, because I am definitely sure that my image is a 
tiled image. I have double-checked this with gdalinfo.

Calling gdaladdo afterward on the file works OK, though, so I suppose 
something has changed in the swig/python wrappers...

Btw this is on linux, pretty recent gdal from svn (rev. 15069), bigtiff 
enabled.

Cheers,
Vincent.
