Bart,

If you can file a ticket on this, and provide a pointer to the problem dataset
I'll treat this as priority to fix before the soon to be released GDAL 1.5.1.

There have been some improvements to the tile decoder for arc/info grids for
1.5.0 but with no specifications and only a haphazard assortment of test data
it is hard to be sure one improvement doesn't break some other case.

Best regards,
