Well, looks like the themedata.xml isn't correct. It caused my GnoMenu to crash and revert to default settings. Actually the whole theme block is missing =) Right one:

<?xml version="1.0" ?>
<content type="Button">
<ContentData Name="Debian Orb v2" Author="Alex Diaz" Copyright="GPL" id="Contentdata"/>
<theme Top="1" id="HasTop">
<Background Image="start-here.png" ImagePressed="start-here-depressed.png" ImageHover="start-here-glow.png"/>
<Top Image="start-here-top.png" ImagePressed="start-here-top-depressed.png" ImageHover="start-here-top-glow.png"/>
<Label Name="Start" MarkupNormal="&lt;span foreground='#000' font_desc='Tahoma 8' stretch='normal' weight='bold'&gt; &lt;/span&gt;" LabelX="20" LabelY="1"/>
</theme>
</content>

Also I don't think you need to have this label "Start" on the button, so I replaced it with a space. (It's "Label" section.)

I absolutely love this. Too bad I don't use Debian, and it'd be a little wierd to have it. lol.
