David,

QGIS automatically wraps up GDAL datasets that are not north-up oriented (i.e. 
if geotransform[2] != 0 or geotransform[4] != 0 or geotransform[5] > 0) as a 
warped VRT (with GDALAutoCreateWarpedVRT()) so as to have a north-up oriented 
dataset to handle, which is the likely reason for the stack trace you get.
