Please describe the problem:
adding a launcher to a panel without specifying an icon results in an invisible launcher. ~/.gnome2/panel2.d/default/launchers has an appropriate .desktop file, and editing that file so that it does have an icon causes it to appear on the panel.

Steps to reproduce:
1. right click on panel, select "add to panel".
2. select "custom application launcher"
3. enter a name "test" and a command "test", but don't specify an icon
4. click OK


Actual results:
no launcher appears in the panel, although the following is written to ~/.gnome2/panel2.d/default/launchers/test.desktop:

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Name[en_GB]=test
Exec=test
Name=test


subsequently appending "Icon=gnome-unknown.png" to this file causes the launcher to appear - so the correct icon does exist.

Expected results:
the launcher should appear with the default icon "gnome-unknown".

Does this happen every time?
yes.
