Re: 2.17.6: assertion failed with \glissando

[Werner LEMBERG]

This time I tried with current git (commit 436824b8):

>>   \version "2.17.6"
>> 
>>   {
>>     f2 \glissando
>>   \override NoteHead #'stencil = ##f

and I still get

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

I'm on a GNU/Linux box, running `autogen.sh' with
`--disable-optimising', and compiling with g++ 4.6.2.

Regardless whether this useful or non-sensical input, there shouldn't
be a failed assertion.
