$ sudo rm /usr/bin/thunderbird
The facts are that :
- gnome-default-applications-properties looks for mozilla-thunderbird and thunderbird executables and show corresponding entries in the menu ("Mozilla Thunderbird" and "Thunderbird"),

$ strace gnome-default-applications-properties 2>&1 | grep thunderbird
$ dpkg --listfiles thunderbird
