Details:

If you create a DenemoDirective (with the Other->Insert LilyPond command)
with some text in the postfix field and then delete that text in the LilyPond
window, and then delete the directive itself via the EditDirectives->Delete
button there is a crash due to a memory corruption as it tries to free the
postfix string.
Just deleting the directive with an ordinary del or backspace key does not
seem to provoke the problem.

This appears to be a thorny bug: the postfix field of the DenemoDirective
appears to have a different value in it from the value it has on leaving the
LilyPond window.

The edit directives code is the newest code, so the suspicion must be that
that code has some bug.

It is present in 0.8.4
