Try updating you GDAL files. Also check to ensure you don't have files 
on your system that are older that are higher up the system path than 
the FWTools versions.

http://trac.osgeo.org/gdal/ticket/3796

Also from what I can tell there is a 10 charaxter limit on older 
versions of ogr2ogr filenames. Name your files something else that  is 
shorter. Rename the files to something else after the conversion.
