[Zope] problems with images and PIL

[Lauri Posti]

Hi,

There is a strange problem with PIL. a code similar to

-----
def foo(im):
sio=StringIO.StringIO(im)
i=PIL.Image.open(sio)
i.resize((newx,newy))
of=StringIO.StringIO()
i.save(of,"jpeg")
return of.getdata()

------------
Throws following exception inside Zope but works well in plain python.
Any suggestions?
