ImageSpecField with source null=True and blank=True

[aronchi]

In my model I have a primary image and some optional ones:

foto = ProcessedImageField(upload_to=update_filename, processors=[ResizeToFit(800, 600,upscale=False)], format='JPEG', options={'quality': 80}    )
foto2 = ProcessedImageField(upload_to="photos/%Y/%m/%d/", help_text="Optional foto", processors=[ResizeToFit(800, 600,upscale=False)], format='JPEG', options={'quality': 80}, blank=True, null=True)

each one have a thumbnail:

foto_thumbnail = ImageSpecField(source='foto', processors=[ResizeToFill(170, 170)], format='JPEG', options={'quality': 80})
foto2_thumbnail = ImageSpecField(source='foto2', processors=[ResizeToFill(170, 170)], format='JPEG', options={'quality': 80})

But if I don't have a foto2

I get a runtimeError:

RuntimeError: maximum recursion depth exceeded while calling a Python object

This is a piece of my trackback:

Thanks in advance, best regards

I can't seem to reproduce this. What versions of Django are you using? Also, can you share any relevant configuration? Thanks!

Can you show me where foto2_thumbnail is being accessed? (Template, etc.)
