Error while uploading a png image

[andresgsaravia]

Here is the tracelog, I'm still not sure how to reproduce it since I can upload images without any problem.

Traceback (most recent call last):

I get this same error while uploading files (e.g. pdf) that are not images. Maybe I should just try to catch the TransformationError and display a dummy image in that case...

Here is the traceback:
