20443	Featured image cannot be set if WordPress install path contains spaces	rosshanney	ryan	"If WordPress is installed in a directory with a name that contains spaces (""/home/username/public_html/path with spaces"", for example), the Featured Image meta box displays only a PHP warning, preventing a Featured Image from being set.

The warning is as follows, and seems to appear with or without WP_DEBUG enabled:

{{{
Warning: sprintf() [function.sprintf]: Too few arguments in C:\path\htdocs\path with spaces\wp-admin\includes\post.php on line 1149
}}}

I think this is caused by the extra % characters introduced after encoding the URL from `get_upload_iframe_src`, which confuse the subsequent `sprintf` calls.
