bonjour, I attached postrm script for bittorrent{,-gui} that should allow the removal of link created by update-alternative in postint script. They maybe need to be checked (not sure they completely remove everything).
bye Olivier PS: by the way you should also put in postrm script : if [ -x /usr/sbin/update-mime ]; then update-mime fi as asked in update-mime manpage.
