I just upgraded a site to umbraco 4.9, and now inline xslt transformations no longer work. No output is returned and the following error shows up in the debug trace.

ItemRenderer   Error rendering Item 1 (NodeId '' : headline).
Could not find any resources appropriate for the specified culture or the neutral culture.  Make sure "Umbraco.Web.umbraco.templateControls.Resources.resources" was correctly embedded or linked into assembly "umbraco" at compile time, or that all the satellite assemblies required are loadable and fully signed.

The control that triggered this error worked in 4.8, it looks like this:

<h2><umbraco:Item ID="Item1" Field="headline" runat="server" Xslt="frie:FinalizeText({0})" XsltDisableEscaping="true" /></h2>

Somehow 4.9 breaks the inline xslt, insights and help is welcome.
