Save as shapefile fails if field names are longer than 10 characters

Description
If I try to save the attached MapInfo file, I get:
Export to vector file failed. Error: trimming attribute name 'PM10_AVG_max' to ten significant characters produces duplicate column name.
and export fails. It seems a limitation of OGR, but perhaps we could be smarter and replace the last character with a serial. Otherwise better forward this ticket to GDAL trac?

Replying to pcav:

AFAIK it's not a limitation of OGR, but a limitation of D-Base format.

I mean: the lack of a proper truncation method, adding a serial in case of too long field names, may be a limitation of OGR.

If the ticket is filed against GDAL, I can have Chaitanya look into clean logic for disambiguation for shortened names.

If this is fixed in OGR we need to keep in mind to adapt http://trac.osgeo.org/qgis/browser/trunk/qgis/src/core/qgsvectorfilewriter.cpp#L312 accordingly.

Apparently the problem has been solved in GDAL 1.7. The method in QGIS should then be updated. See http://trac.osgeo.org/gdal/ticket/3796#comment:1
BTW, the external plugin Table Manager fails to rename the fields, hanging QGIS
