Performed a Kubuntu Minimal install.

The KDE >> Internet menu didn't show an icon for Mozilla Thunderbird.

dpkg-query shows that Mozilla Thunderbird is installed:

root@kubuntuvm:~# ls -la /usr/bin/thunderbird
ls: cannot access '/usr/bin/thunderbird': No such file or directory

root@kubuntuvm:~# dpkg -L thunderbird | grep /usr/bin/thunderbird

Removing and re-installing the thunderbird package fixes the issue.
