+
+    New cleanup in "akonadictl fsck": clean up orphan resources from the DB
+    
+    The only way this can ever happen is when hacking agentsrc and removing
+    resources from it (or removing the whole ~/.config). But then you get
+    dead collection trees in kmail, always red, always unusable, and this is
+    the only way to clean this up.
