New issue 2983 by address@hidden: assertion failed with \glissando
http://code.google.com/p/lilypond/issues/detail?id=2983

[commit 436824b8]

The following code

  \version "2.17.8"

  {
    f2 \glissando
  \override NoteHead #'stencil = ##f
                  e |
  }

causes the following output (beautified):

  GNU LilyPond 2.17.8
  Processing `bug.ly'
  Parsing...
  Interpreting music...
  Preprocessing graphical objects...
  Finding the ideal number of pages...
  Fitting music on 1 page...

  lilypond:
    ../flower/include/interval.hh:226:
      T Interval_t<T>::center() const [with T = double]:
      Assertion `!is_empty ()' failed.

Keith has posted a small patch in

  http://lists.gnu.org/archive/html/bug-lilypond/2012-11/msg00067.html

which avoids the assertion failure.
