New description:

 map_meta_cap is not prepared to handle missing or invalid post ID's. To
 duplicate this, delete a post from the posts table without deleting its
 attached comments, then visit the admin dashboard with the recent comments
 widget visible.

 Update: this isn't something that happens naturally in WordPress core, but
 is something plugins are able to do directly to the database, which
 results in orphaned comments. The attached patches only suppress debug
 notices PHP spits out, and does not directly address the issue of what to
 do with orphaned comments, should a plugin choose to do this.
