22503	wp_mime_type_icon() fails to properly cache icons	nacin	nacin	"It does this:
{{{
$icon_files = wp_cache_get('icon_files');
}}}
And:
{{{
wp_cache_set('icon_files', $icon_files, 600);
}}}

See the issue? I spent an embarrassing amount of time debugging the caching backend before I did. The timeout of ""600"" is actually the cache group in that call. We need to slip in a 'default' there.

Noticed while doing profiling for #22186. If you're calling this function for a whole bunch of attachments, all of those repetitive disk scans can slow things down quite a bit."	defect (bug)	closed	normal	3.5	Cache		normal	fixed
