Photoshop reports an unsupported coding, exiftool shows some more details:
Encoding Process: Extended sequential DCT, arithmetic coding

Maybe your output codec quality setting is a little bit low. From your .pto file's  'p'- line (which is describing the output image)
n"JPEG q0"
I'm not sure about the current JPG codec quality scheme (0-high,1-normal,2-low or 0-100) but what happens if you try 
n"JPEG q0"
instead?

Other than that this may also have to do with the JPG library in use.

OTOH it's usually best practice to output a non degrading file type like
TIFF (LZW compression works well for 8bit files). This allows for some
editing and further cropping, then save a JPG (sRGB) copy to display
online etc.

Cheers,
Carl

Title:
  Jpeg files created with the panorama tool are correctly read and
  displayed by digikam but are wrong and are not readable by other
  softwares

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  When creating panorama, I get nice files (.jpg) that I can display and manipulate with Digikam. However, this files seems to have a problem, and they can not be read outside Digikam. I tried to send them to other users, and they can not read them etheir.
  It seems that gnview can read them, but not Firefox, neither most of windows programs. Ubuntu can not create miniatures, and the default Ubuntu image display software can not open them either. Something seems to be wrong in the file format.

  Reproducible: Always 
  Steps to Reproduce: 1. Create a panorama 2. Save it
  I'm using the latest stable Hugin release, under Ubuntu 13.10.
  See the attached jpg file as an example.
