First of all, please don't post binary attachments in this newsgroup
(povray.binary.images can be used for this). Furthermore, jpg is the preferred
format.  

Concerning your problem, I would estimate, the "scale 0.025" in the normal
statement probably causes a rounding error responsible for the strange
behaviour.  But i'm not sure about it.  

For example 
normal { granite 0.15 scale 0.1 }
looks much better although there are still strange things happening :-)
