Can't add launcher icon for git gui

[Russell Briggs]

This is a usability issue in 2 parts:

1. I would like to add a Launcher icon for git-gui, however when I use the 'Lock to Launcher' option and close the GUI, the launcher icon disappears.

2. There is no easy way to create a custom launcher icon
(Creating a .desktop file in a non-obvious location is not an easy way! Not least because I have no idea what icon to use, and the default icon is uuuugly!)

I'm assuming my system info is filed with this bug via apport, but just in case, I am on Ubuntu 14.04 (Unity 7)

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm the "git gui" icon problem.

A utility to create a custom icon is an ideal small project for someone looking for something to do. It's not a part of what a desktop shell does, though, and since Unity just follows the Free Desktop standards on .desktop files, useful as a standalone utility without reference to Unity.
