Undefined?

[slimjim]

I see it (very rarely) when uploading pics into an album. I will see the bar at he top showing the % loading but when it's finished instead of the usual "meta data" or whatever it is called (as in the pic below) it shows "undefined" as in the examples above and if you click on an undefined image it deletes




As I said before repeating the upload for the same pic usually works fine.
