media_get_browser_plugin_info() returns an empty array

This happens quite sporadically and I have not been able to reproduce it locally yet.
What happens is that an empty array is cached and breaking media browser when it should be rendered.

I dont know why its cached an empty array yet, but I thought it still could be good with a check if the cached data is empty.

Something like this? (media.module 1285):

if ($cache = cache_get($cid) && !empty($cache->data)) {

I've never done a patch before, but I post one as soon as I learned how to do ... :)
