i have a edit_profile view at my django application that also checks if the pgp key the users saves to his profile is in RSA format, Anyways if i add a profile avatar for the very first time it works like a charm, if i want to clear or delete it, im always jumping onto the execpt block and the user avatar remains unchanged. Well i dont see a clear reason why at the point can maybe smb give me a hint here:

raise ValidationError(u'Unsupported file extension. Allowed types are: .jpg, .jpeg, .png')

limit = 2 * 1024 * 1024
if value.size > limit:
