Comment (by xnau):

 I ran across this error and i traced it to a problem with the "sizes"
 array within the attachment metadata. The metadata for an image that was
 triggering the notice looked like this:

 array (
   'width' => '400',
   'height' => '340',
   'hwstring_small' => "height='96' width='112'",
   'file' => 'default-image.jpg',
   'sizes' =>
   array (
     'thumbnail' =>
     array (
       'file' => 'default-image-150x127.jpg',
       'width' => '150',
       'height' => '127',
     ),
     'medium' =>
     array (
       'file' => 'default-image-200x170.jpg',
       'width' => '200',
       'height' => '170',
     ),
     'large' => '',
     'small-thumb' =>
     array (
       'file' => 'default-image-88x75.jpg',
       'width' => '88',
       'height' => '75',
     ),
     'micro-thumb' =>
     array (
       'file' => 'default-image-47x40.jpg',
       'width' => '47',
       'height' => '40',
     ),
     'product-slide' =>
     array (
       'file' => 'default-image-376x320.jpg',
       'width' => '376',
       'height' => '320',
     ),
     'post-thumbnail' =>
     array (
       'file' => 'default-image-141x120.jpg',
       'width' => '141',
       'height' => '120',
     ),
   ),
   'image_meta' =>
   array (
     'aperture' => '0',
     'credit' => '',
     'camera' => '',
     'caption' => '',
     'created_timestamp' => '0',
     'copyright' => '',
     'focal_length' => '0',
     'iso' => '0',
     'shutter_speed' => '0',
     'title' => '',
   ),
 )

 (note the 'large' image size missing it's array)

 If I remove the empty size definition element, the notice stops. The
 question is how did the metadata get corrupted in the first place? I think
 it was possibly caused by a plugin I was using to rebuild the thumbnails
 (AJAX Thumbnail Rebuild). More testing is needed, but I thought I'd report
 my findings.
