I’m working on a Facebook Application that generates wall posts. In testing these posts, I’ve discovered that the Facebook Platform action of “liking” a post is failing. The specific error message is

Object cannot be liked
Unable to
like this object because it is not
accessible (it may have been removed
or you may no longer have permission
to see it).

Neither of the conditions suggested in the error are actually true.

Googling for the error returns zero results(!) (EDIT! Now returns a result – this question)
Searching the Facebook bug repository returns zero results. (EDIT! Returns one result now because I reported this bug)
Searching the Facebook community forums yields two posts neither of which address this specific issue.

These wall-to-wall posts are generated via stream.publish using their PHP library. Here’s a sample of the API call from my production code

$this->facebook->api_client->stream_publish(
    ''
  , array(
        'name'        => 'Sample Wall Post'
      , 'description' => 'Just a test description'
      , 'media'       => array(
          FbAppHelper::imageAttachment( 'path/to/image.gif', 'http://apps.facebook.com/' . FB_CANVAS_URI )
        )
    )
  , null
  , $facebookId
);

Any clues?
