Hello Jason,

 I cannot reproduce this behaviour. I move the mouse and quickly press "[" (in 
empty sky) and move the mouse and quickly press "]" (If you use "[" and "]" 
you do not need to be on an object, the empty sky is OK). I always get 
distances greater than 0. I have also tried on objects when the transient 
label is appearing and it also works here. I will try again with greater 
zooms or other conditions to try to reproduce this behaviour.

Yes, that is right this is a bug, I have to fix this.
