Solaris PIL JPEG Problems

[BRAINIAC]

I am trying to process JPEG images using PIL 1.1.4 with Python 2.2.3.
GIF and PNG are working fine. I am using jpeg-6b and all my other
software using libjpeg work fine.  I am thinking you need much more
info to help me, but let me start with this:

Python 2.2.3 (#2, Feb  3 2004, 03:09:11)
[GCC 2.7.2.2] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import Image
>>> a=Image.open("lena.jpg")
>>> a.size
(128, 128)
>>> a.info
{'jfif_version': (1, 1), 'jfif': 257, 'jfif_unit': 0, 'jfif_density': (1, 1)}
>>> a.save("lena-test.jpg", "JPEG")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/opt/lib/python2.2/site-packages/PIL/Image.py", line 1125, in save
    self.load()
  File "/opt/lib/python2.2/site-packages/PIL/ImageFile.py", line 192, in load
    raise IOError(error + " when reading image file")
IOError: decoding error when reading image file

Here is output from another session in which GIF and PNG work fine:

>>> a=Image.open("lena.gif")
>>> a.info
{'version': 'GIF87a', 'background': 0}
>>> a.save("lena-test.gif")
>>> a.save("lena-test.png", "PNG")
>>>

Thanks !
