Comment:

 Ouch, well spotted. I only focused on the x,y coordinates, took me 2 hours
 ;-)
 And ofcourse the ST_Isvalid doesn't involve the Z. Luckily, the
 ST_IsClosed function also does the job of checking.

 I'm going to dig to the source of this problem, since in theory this one
 should be closed.
