RipperX installed but not showing up in Dash

I've just installed RipperX from Synaptic.

The program is installed:-

carl@number5:~$ which ripperx
/usr/bin/ripperx

And will run with ripperx from the terminal.

But it does not appear in the Dash at all.

The closest question to this is this one but that relates to non-GUI applications.

Is there something I need to do to get it to show up in Dash, or is this a bug/problem with RipperX itself?

This question has been suggested as a duplicate but the answer links to this question, which starts with the caveat Please note that right now, most of the information contained below is outdated and cannot be updated. Be careful, most of this won't work on Ubuntu 12.04 and newer. I am running 15.10

Additional:-

carl@number5:~$ sudo find /usr -iname ripperx.desktop
[sudo] password for carl: 
/usr/share/applications/ripperx.desktop
