can't open .img files (ERROR 1: Unknown base item type : 4)

Description
When attempting to open an ERDAS file created by ArcGIS (.img) gdal.Open() returns the following error:
ERROR 1: Unknown base item type : 4
This has been discussed here: http://www.mail-archive.com/gdal-dev@lists.osgeo.org/msg06843.html
and is evident in gdal_translate here: http://www.mail-archive.com/gdal-dev@lists.osgeo.org/msg04124.html
This is reportedly something to do with the BASEDATA object in the file.
Is there a fix / workaround? What further information (sample files?) would be useful?
lib-gdal 1.7.2, python-gdal 1.7.2 in Ubuntu 9.10 (32-bit)
Many thanks.

I've now attached the IMAGINE image file's .xml and .dbf files generated by ArcGIS' Spatial Analyst. I can't attach the image file as it's too large (~6mb), are these enough? This only seems to occur for us with some IMAGINE image files created by Arc's Spatial Analyst. Thanks.

No, those .xml and .dbf files are ArcGIS internal stuff not recognized by GDAL. Only the .img is the exchange file... You can perhaps try posting it on filebin.ca or another upload site.

OK, thanks for letting me know. You can download the image file from here: http://filebin.ca/skvcex/uib_sca_2000M03.img Really appreciated the help.

I have the file and have reproduced the problem. It should be straight forward to correct.

Just to confirm and say thanks - updated GDAL to 1.7.3 from the ubuntugis-unstable PPA and our files are being read without errors.
Yes, as Frank mentionned in the two emails, sample files would be useful to debug this issue.
