[Image-SIG] PIL 1.1.3: putdata with "I" mode images

[Michael Volkmer]

Anyone uses  putdata with "I" mode images ? 
Everytime I try to put the data back to the image I get the following error:

 >Traceback (most recent call last):
 > File "./data_test.py", line 9, in ?
 >im2.putdata(data1)
 >  File "/usr/lib/python2.2/site-packages/PIL/Image.py", line 661, in 
putdata
 >    self.im.putdata(data, scale, offset)
 >TypeError: unrecognized image mode

Even applying putdata after getdata from the same image without any 
changes doesn't work.
My workaround is  to use getpixel/putpixel but this becomes really slow.
PIL version is 1.1.3
