I did some poking into this tonight, and it looks like this started happening in 0.0.24 when the gconf entries for max_port and min_port were added. Previously there were just command line options that were specified as defaulting to 6881-6889 (gnome-btdownload-0.0.22/man/gnome- btdownload.1). In reality it looks like the previous gnome-btdownload just fell back to the defaults for the python BitTorrent module, which seems to be 6881-6999 ( BitTorrent-3.4.2/BitTorrent/download.py ).
I downloaded the source for gnome-btdownload 0.0.26 and they changed the schema so that max_port defaults to 6889. -- "Address already in use" error with multiple downloads https://launchpad.net/bugs/57039 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
