ATCT .21 PIL ratio problem

Sorry for asking about a way old version, but I'm stuck.

I'm in Plone 2.05, with ATCT 0.21.  I'm trying to create some images 
with parentDir.invokeFactory(id=imageName,type_name='ATImage')

I end up with an error,

 File "/usr/local/zope/lib/python/Products/Archetypes/Field.py", line 
2269, in scale
    image.save(thumbnail_file, format, quality=self.pil_quality)
  File "/usr/lib/python2.3/site-packages/PIL/Image.py", line 1136, in save
    SAVE[string.upper(format)](self, fp, filename)
  File "/usr/lib/python2.3/site-packages/PIL/PngImagePlugin.py", line 
445, in _save
    ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, 
rawmode)])
  File "/usr/lib/python2.3/site-packages/PIL/ImageFile.py", line 385, in 
_save
    e.setimage(im.im, b)
SystemError: tile cannot extend outside image

my googling seems to indicate that this is a PIL bug that happens when 
trying to create images with 'not so common' ratios such as (i.e. 600x15)

has anyone here came up with a workaround?

I appreciate it,
