This bug can also generate a hang:
create an equation which uses [C_PI].
Edit the equation so that it no longer uses [C_PI].
Now create a new equation which uses [C_PI]: hang on [OK].

It looks like on apply equation edit, kst locks all scalars which were used by the equation, re-parses the equation, and then attempts to unlock all of the scalars which are now used.  So
  -adding a scalar causes an attempt to unlock a not-locked scalar.
  -removing a scalar leaves it locked.
