Hi,

using 6.4.svn (~6.4.2rc3), utm 32N + wgs84, your region bounds, and synthetic elevation data (gaussian mound from r.surf.volcano) it works for me. (debian/squeeze 64bit)

fixed by #800 ?

I have made a test in a Piemonte UTM location with the current 6.4.svn, no (more) problems

Closing as fixed.
