Media thumb reporting wrong height


#1

A user noticed when uploading a picture to twitter that my client was stretching the image.
Looking at the raw json for the tweet

          }
        }
      }
    ]
  },
...
}

the height for thumb is too large, opening http://pbs.twimg.com/media/BIhH33dCUAIL4MR.png:thumb shows a 150x44 image
I assume it’s bugging because the height of the original is 141 which is less than 150?
