Hello, first - GRASS version, OS, Arch? second - have tested with GRASS 7? third - if dataset is small, TGZ it and drop somewhere for testing (opening an issue in trac would also be fine).
I have dataset that fails to work with salesman in 6.4.1. I had no time to make tests with 6.5 and 7. Issue is different - it reports some nodes to be unreachable after extensive v.clean and v.digit cleanup. Migh be interesting to collect sample data that causes v.net.* to fail to try isolate root cause(s) of such failures.
