Initial Comment:
r.in.xyz has been segfaulting with a particular dataset. It's quite big (23 MB bzipped) and I don't know how to provide it but let me know if ther's a need+way to.

Details:

$r.in.xyz -g input=tin_nieciag.xyz output=tin_nie ciag.xyz method=min type=DCELL fs="|" x=1 y=2 z=3 percent=100

n=5725102.149034 s=5705608.286234 e=587119.577053 w=568715.830892 b=69.431216 t= 224.696106

$ g.region n=5725102.149034 s=5705608.286234 e=587 119.577053 w=568715.830892 res=1 -a

$ gdb r.in.xyz
$ run input=tin_nieciag.xyz output=tin_nie ciag.xyz method=min type=DCELL fs="|" x=1 y=2 z=3 percent=100
