Hi all. v.buffer input=fiumi at paolo type=line layer=1 distance=5000 output=fiumi_buf takes *ages* to process. You can find the location, with only the vector fiumi at: http://int.faunalia.it/~paolo/sample.tar.gz . Tested on debian testing (6.4.0~rc5-3). All the best. -- Paolo Cavallini: http://www.faunalia.it/pc
