Fatal error: Unsupported operand types in media.browser.inc

I'm getting an error when a user who does not have either 'administer files' or 'add media from remote urls' attempts to open the media browser dialog. When the user does not have access, remote_stream_wrapper_media_browser_plugin_view() returns null. This causes an error in media_browser when it attempts to append the result to an array.

At some point, the default "return array();" was dropped from the end of the function. My patch adds it back in—this seems to be what other media browser plugins do.

patch to follow...
