[Image-SIG] PIL bug report: touble in save jpeg file with quality=100 and optimize=True

[Daniil Osokin]

Hello

I have try to save jpeg file with quality=100 and optimize but get this:
-----------------------------------------------------------
Traceback (most recent call last):
  File "D:\temp\Python-PIL-test\pil_test.py", line 29, in <module>
    main("image_test.jpg")
  File "D:\temp\Python-PIL-test\pil_test.py", line 23, in main
    img.save(file_out, "JPEG", quality=100, optimize=True)
  File "C:\Python25\Lib\site-packages\PIL\Image.py", line 1405, in save
    save_handler(self, fp, filename)
  File "C:\Python25\lib\site-packages\PIL\JpegImagePlugin.py", line
409, in _save
    ImageFile._save(im, fp, [("jpeg", (0,0)+im.size, 0, rawmode)])
  File "C:\Python25\Lib\site-packages\PIL\ImageFile.py", line 493, in _save
    raise IOError("encoder error %d when writing image file" % s)
IOError: encoder error -2 when writing image file
-----------------------------------------------------------

But this lines work fine:
img.save(file_out, "JPEG", quality=80, optimize=True)
or
img.save(file_out, "JPEG", quality=100)

PIL version 1.1.6
Python 2.5.4
Windows XP SP3

test files are attached

Thanx
