  * keywords:  => ftools, vector
  * type:  bug => patch

Comment:

 This is related with #2629. Also here is another problem: when field names
 trimmed and suffix added we will have duplicate names and get error when
 initialize shapefile writer. I found three tools with this problem: union,
 intersection, symmetrical difference

 Patch to fix this problem (evaluate field name lenght, check for
 duplicates and display warning messages) attached
