The use of the candenza section in the snippet seems incorrect, as it 
messes with the timing.

Here's my take using scaled durations and some additional tweaks:

%%%%
\version "2.19.82"
\paper { ragged-right = ##t }
\fixed c' {
  \time 3/4
  | c'4 c'
    c'4*1/2-\tweak style #'zigzag \glissando
    \single \hideNotes
    \tweak X-offset #2 \tweak X-extent #'(0 . 0)
    c4*1/2
    \break
  | c'4 c' c
}
%%%%

And here's the same approach applied to your scenario:

%%%%
\version "2.19.82"
\paper { ragged-right = ##t }
\fixed e' {
  | e8 [ e8 e8 d8 ] g4 ^^ e4 ~ \bar ":|."
  | \mark #1
    e4*1/2-\tweak style #'zigzag \glissando
    \single \hideNotes
    \tweak X-offset #2 \tweak X-extent #'(0 . 0)
    e,4*1/2
    r4 r2
}
%%%%

The issue with the unterminated tie can be resolved by being explicit 
about voice creation:

%%%%
\version "2.19.82"
\paper { ragged-right = ##t }
\new Voice = "foo" \fixed e' {
  | e8 [ e8 e8 d8 ] g4 ^^ e4 ~ \bar ":|."
  <<
    \context Voice = "foo" { | e4 b4\rest b2\rest }
    \new Voice {
      \voiceTwo \hideNotes
      | \tweak X-offset #-1.5 e2 -\tweak style #'zigzag \glissando e,2
    }
  >>
}
%%%%
