mouse over enum declaration bug

When mousing over an enum declaration in an extended for loop i.e. mouse over Axis in

got an exception thrown (see below) seems to occur else where as well. nb I have posted a tracker as well is this using the IDEA bug reporter. What is the correct thing to do.... I am not quite sure of the etiquette here.
