I just got the above error after deploying a custom site definition.
Within the publishin feature I didn’t have AvailablePageLayouts set. I’m assuming that SharePoint tries to pick up a default layout which doesn’t exist.
Changing:
<Property Key=”AvailablePageLayouts” Value=””/>
To: <PropertyKey=“AvailablePageLayouts“Value=“~SiteCollection/_catalogs/masterpage/MyLayout.aspx“/>
fixed the issue.
