Please, whenever you report errors, also report the command line used.

The DV2 and DV4 maps seem to be there twice and so there are duplicate 
column names, leading to a failure in the CREATE TABLE call.

In the call to i.segment.stats, did you maybe add these map names twice 
to the 'rasters' parameter by accident ?
