I can see no effect of this; possibly merely a warning ?

In the mentioned line there is a call to glob() to enumerate the feed cache files. glob() can return false which could have caused these warnings. A harmless situation where this can happen would be that there are no cache files and open_basedir restrictions are in effect. I added a check before foreach() to make sure glob() returned an array:

If you want to try it please remember that it is needed to rebuild the theme to apply the changes. Only the changes in function feed_cache_cleanup() are related to this issue.
