#80 TiffTagProcessingException

[Dan Berger]

Attempting to use jUploader to resize and upload JPGs created from a Canon Rebel XSI (450D) via Bibble (http://bibblelabs.com/), I get the following exception during resize:

Could not scale photo img_0144.jpg because au.com.lastweekend.jim.io.exif.TiffTagProcessingException: 3 tags, from offset 20062exceeds data length 20104

dismissing the dialog allows upload to proceed, the image is uploaded, but is missing EXIF data.

I've tried this with both the 1.1.2 and 1.2 alphas with identical results.

I'm happy to provide a sample image via email (it's a 12MP camera, so the file is rather large).

as an aside, exiftool seems to read the EXIF tags ok, producing the following output:

Seems it was something about the thumbnail image in the EXIF data, using exiftool and stripping said thumbnail allowed jUploader to process the files.

I do still have a "broken" sample image, if desired.
