Yeah there is currently an error that pops up if you select an object that was not able to get meshed, so that its quick bounding box was not available.

It was an error in the display of the bounding size display in the properties panel in the upper-right area of the window (the bottom line that says Size:)

It's fixed up for the next v2 beta though.


So B-W, that is probably what you ran into, must have selected a little tiny degenerate left over fragment from a boolean.
