I've only seen it once.  Imagine the whitish color of ice that 
contains lots of microscopic air bubbles.  It is not large, just a 
spec in the tube.  Lily had it at once at a spot in the tubing that 
had been crimped.  That is... the tube had a permanent deformation 
that would not come out. The crystal(s) formed there and the tube was 
blocked.  The pump complained when she tried to bolus for a meal. 
That was a couple of years ago.
