[Image-SIG] im.show() error

[bas pels]

hi,

after upgrading PIL 1.0b to PIL 1.0, i cannot longer pass the first page of
the tutorial...
any idea what happened?


[bas@orius bas]$ python

python >> import Image
python >> im = Image.open("lena.ppm")
python >> print im.format, im.size, im.mode
PPM (128, 128) RGB
python >> im.show()

strange enough, the following works fine:
