Hello, did specify any CAPTCHA related settings in your config? 

Also, which version of PIL is installed?

from PIL import Image
Image.VERSION


Finally, could you please also try and run 'manage.py test captcha' and report 
back the results?

I have PIL 1.1.7
The bug is with the function rotate in image.py but i can not fix it.

The concerned line: charimage = charimage.rotate(random.randrange( 
*settings.CAPTCHA_LETTER_ROTATION ), resample=Image.BICUBIC)

Would you mind testing this against the svn version of simple-captcha?

You can remove the Antialiasing in the file "image.py" like this:

charimg = charimg.rotate(random.randrange(*(-30, 31)), expand=1) # , 
resample=Image.ANTIALIAS)

Sorry for duplicate posting, you can resolve with this line:

charimg = charimg.rotate(random.randrange(*(-30, 31)), expand=1, 
resample=Image.BICUBIC)

Have fun!
