Hi Michal;

I just tried to duplicate this old bug on emacs 24.3 and I couldn't. Can
you still duplicate it? If so, a test message would be appreciated. I
think if it's 24.2.1 specific, we can call it fixed.

The relevant part of my test image json is 


            {
                  "content-charset" : "utf-8",
                  "content-length" : 3619,
                  "filename" : "spiral.svg",
                  "content-type" : "image/svg+xml",
                  "content-transfer-encoding" : "base64",
                  "id" : 1
               }
