PIL - Image.open() problem

Hi everybody.

It seems I don't know Python well enough yet. I have a problem with
Python Imaging Library which probably is simple. Only not for me!

Problem: I have a method in a classe which sometimes open a JPEG image,
and at other times do not.

When it doesn't work it is always in the same mode, which leads me to think
that I somehow don't initialize the PIL library.

The imports and method is shown below together with the stacktrace. Any
pointer as to where to look for the error is most welcome

                print "Opening succeeded!"
            return self.picture
            return None
