Bug description:
  I noticed this warning message when deleting a journal. I'm not sure
  whether the journal has to have embedded images in an entry or not,
  but here's what I did.

  1. Create a journal
  2. Create a journal entry
  3. Use the TinyMCE image button to embed an image in the journal entry
  4. Select the journal entry in a journal entry block on a page
  5. Delete the page
  6. Delete the journal

  Result:

  [WAR] 75 (lib/embeddedimage.php:176) Invalid argument supplied for foreach()
  Call stack (most recent first):
