I can confirm that it works both for converting RGB images and for
creating new YCbCr images in Oneiric Ocelot.
Wonderful news!

Title:
python2.7 & python imaging (PIL) dumps core with buffer overflow
Status in “python-imaging” package in Ubuntu:
Fix Released
Status in “python-imaging” source package in Natty:
Confirmed
Status in “python-imaging” source package in Oneiric:
Fix Released
Bug description:
Binary package hint: python2.7
Python 2.7 dumps core when doing python imaging (PIL) operations on a
TIF file. Below is a sample doing a resize; but another operation like
converting the color mode will also dump core.
The unusual color mode may be contributing to the bug.
This cannot be replicated under maverick, where it works as expected.
I will either attach the TIF file to this bug report, or if too large,
I will link to it elsewhere.
>>> from PIL import Image
>>> image = Image.open('/home/damon/tmp/samsung.tif')
>>> image
<PIL.TiffImagePlugin.TiffImageFile image mode=YCbCr size=3872x2592 at 0x2904128>
>>> image.thumbnail((242,162), Image.NEAREST)
