I was getting this error

[error] [client 155.52.208.80] PHP Fatal error:  Unsupported operand types in /path/to/drupal/sites/all/modules/views/plugins/views_plugin_row_rss_fields.inc on line 123

I added this to the render() function in views_plugin_style_atom_fields.inc


      // This will be filled in by the row plugin and is used later on in the
      // theming output. copied from views_plugin_style_rss.inc
      $this->namespaces = array('xmlns:dc' => 'http://purl.org/dc/elements/1.1/');

It was trying to add other namespaces but $this->view->style_plugin->namespaces was not defined

The offending statement was
$this->view->style_plugin->namespaces += $xml_rdf_namespaces; should be
$this->view->style_plugin->namespaces = array_merge($this->view->style_plugin->namespaces, $xml_rdf_namespaces); since I don't think you can '+=' an array that doesn't already exist.

Patch to follow shortly

Here is the simple patch. This patch produces the following warnings: Warning: array_merge() [function.array-merge]: Argument #1 is not an array

I will replace this patch to correct this.

None of the patches in this issue worked for me.

There appears to be a related issue directly in the Views issue queue. I submitted a patch to Views in that issue that resolved the issue for me.

After running into other similar errors with this module, I am attaching a patch to the Views Atom module itself, which initializes the namespace array in the Views display plugin.
