 Tiff is a quite a complicated format. Its implementation can contain
 vulnerabilities.

 Some man creates tickets with tiffs attached:
 #23140, #23085.

 People consider this as an attack. They even ask him in a rude form not to
 post tiffs. Maybe we should protect him from such a rudeness ;) I suggest
 to disallow uploads of non-text formats other than the ones in the
 following whitelist: ["png"].
