Description
Some dataset implementation do not include code to initialize the overview manager ( oOvManager.Initialize ). This makes it difficult to handle overviews in a generic manner.
Adding
poDS->oOvManager.Initialize( poDS, poOpenInfo->pszFilename );
after
poDS->TryLoadXML();
fixes this issue in XPM, GFF, etc.

Frank,
I see I had found a sample available online. See http://trac.osgeo.org/gdal/browser/trunk/autotest/gdrivers/gff.py.
The public page is http://www.sandia.gov/radar/sar-data.html
Note:
See TracTickets
for help on using tickets.
I have added overview support to the XPM (r18239, r18241) and terragen (r18240) to match the changes made by rprinceley in the 1.6-esri branch (r17312,r17313). The other portions of r17312 appear to already be in trunk and were possibly back ported.
While GFF was mentioned in this ticket, and is lacking overview support, I have no test data for this format and I'm hesitant to modify the driver without the ability to test it.
