If this is my mistake, thus I didn't configure shell right ( used wrong parameters or parameters combination) , at least there should be a nicer message telling me what went wrong...

source is:

<component id="shell" type="Shell">
<binding name="delegate" value="delegate"/>
<binding name="title" value="title"/>
<binding name="stylesheets" value="stylesheets"/>
</component>
