The \hideNotes and \unHideNotes is to achieve the work-around for mixing bending strings with hammer-on and pull-offs (which are engraved using normal slurs).  This is just an excerpt of what I was trying to engrave... and I think it is minimal, in the sense that if you remove any one part of it then Lilypond runs fine and produces what I expected.

Ok, then I would write the last lines this way (this avoids the error, by the way):

\bendOff

\shape #'((-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 1)) Voice.Slur

\shape #'((-0.3 . 0) (-0.3 . 0) (-0.3 . 0) (-0.5 . 0.5)) TabVoice.Slur

\hideNotes \grace a( \unHideNotes g )

Adjust the values of \shape

And this is a full example of the workaround. I might add it to the README on Github:

\version "2.18.0"
\include "notation-snippets/guitar-string-bending/definitions.ily"

music = \relative c' {
  \set TabStaff.minimumFret = 4
  \set TabStaff.restrainOpenStrings = ##t
  \bendOn 
  fis8( g)( fis) \bendOff
  \shape #'((-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 0.5) (-0.8 . 1)) Voice.Slur
  \shape #'((-0.5 . 0) (-0.5 . 0) (-0.5 . 0) (-0.5 . 0.3)) TabVoice.Slur
  \hideNotes \grace fis( \unHideNotes e)
}

\score {
  \new StaffGroup <<
    \new Staff { \new Voice { \clef "treble_8" \music } }
    \new TabStaff { \new TabVoice { \clef "moderntab" \music } }
  >>
  \layout {
    indent = #0
    \context { \StaffGroup \override StaffGrouper.staff-staff-spacing.padding = #3 }
  }
}
