Show proper error message in UI when document cannot be loaded

Instead of showing a broken iframe, display a proper error message
when a document cannot be loaded.

This is a preparation step to add special handling if the document is
not found, e.g. in this case we may want to display a 'Create' button
to create the missing document.
