setting scaled image troubles

Hi,

I'm trying to create a ZMSGraphic-like custom-object that auto-generates 
preview images to embed into the text.

I found more or less everything I need. pil_img_resize, ImageFromData.

But after creating a scaled image, I don't seem to be able to set it to 
the custom object as property, let alone invoke getHref on it.

See the below code for a debugging session. Any suggestions?

(Pdb) img = context.getObjProperty("img", request)
(Pdb) scaled_img = context.pil_img_resize(img, (20, 20))
(Pdb) scaled_blob = context.ImageFromData(scaled_img['data'])
(Pdb) p scaled_blob
<MyImage at >
(Pdb) p img
<MyImage at >
(Pdb) context.setObjProperty("scaled_img", scaled_blob, "ger")
(Pdb) context.getObjProperty("scaled_img", request)
''
