Bug report #10039

line intersection fails if ID name is the same

The line intersection tool fails if the field name of the two layers involved in the analysis is the same. Example: if I want to perform the line intersection between field ID of layer_1 and field ID of layer_2, the operation results the intersection for the ID of only layer_1.

See attach for a graphical comparison of the two different results.

It seems also that when you intersect two shapes that have each a column with the same name (e.g. 'ID'), the resulting table does not give attribute-info for both fields in the intersection layer. I changed the name of one of the two fields, and then it was displayed.
In attach you see the attribute table of the intersect. You see ID and id_1 in which only one field is filled..
