Comment 5 for bug 542343

This can easily be fixed by editing the gnome-panel.desktop file

`sudo vim /usr/share/applications/gnome-panel.desktop`

Move the first line ("X-Ubuntu-Gettext-Domain=gnome-panel-2.0") that appears before the group name '[Desktop Entry]' to some point after, for example mine now looks something like this:

<code>
[Desktop Entry]
Type=Application
Name=Panel
Comment=Launch other applications and provide various utilities to manage windows, show the time, etc.
Icon=gnome-panel
Exec=gnome-panel
StartupNotify=true
Terminal=false
