RDFizing breaks View

I am attempting to set up RDF on various views, particularly my blog (which I have a custom view for). Under the style settings for the feed display, I chose "RDF Feed". Upon doing so, I got a ton of error messages:

warning: array_merge() [function.array-merge]: Argument #1 is not an array in /mysite/modules/views/modules/node/views_plugin_row_node_rss.inc on line 117.
warning: array_merge() [function.array-merge]: Argument #1 is not an array in /mysite/modules/views/modules/node/views_plugin_row_node_rss.inc on line 117.
warning: Variable passed to each() is not an array or object in /mysite/modules/rdf/rdf.api.inc on line 1083.
warning: Invalid argument supplied for foreach() in /mysite/modules/rdf/rdf.api.inc on line 409.

with these four messages repeated about 20 times (once per blog post retrieved? I didn't make an exact count).
