Hi Pierre,

in the NR 1.2.6 Special rhythmic concerns, Known issues and warnings
you can read:
"The use of grace notes within voice contexts confuses the way the
voice is typeset. This can be overcome by inserting a rest or note
between the voice command and the grace note."

Seems that changing graceSettings is confused too.
I didn't manage to apply the shown workaround to your example.

But replacing \voiceOne, \voiceTwo with \stemUp, \stemDown works,
although this will lead to some other problems.

So I come up with the code below, containing three suggestions, I'd
prefer `Suggestion II'.
`Suggestion III' is needed only, if you want a complete new definition
of graceSettings.

\version "2.15.38"
\score {
 \new Staff
 <<
%%%% Suggestion I
  % $(add-grace-property 'Voice 'Beam 'beam-thickness '0.5)
  % \override Staff.Beam #'beam-thickness = #0.55
 \new Voice = "first"
   {

      \clef "treble_8"
      \time 3/8
      \stemUp
      e'4. | %2

      \appoggiatura { b'32 [ c'' b' ais' ] } b'8 [ c'' b'16
\glissando e'' ] | %2
   }
 \new Voice= "second"

   {  \stemDown a,8 a, a, }
 >>
%%%% Suggestion II
 \layout {
         \override Beam #'beam-thickness = #0.55
         $(add-grace-property 'Voice 'Beam 'beam-thickness '0.5)
 }
%%%% Suggestion III
%  \layout {
%          \override Beam #'beam-thickness = #0.55
%          \context {
%                 \Voice
%                 graceSettings = #`(
%                           (Voice Stem direction ,UP)
%                           (Voice Stem font-size -3)
%                           (Voice Flag font-size -3)
%                           (Voice NoteHead font-size -3)
%                           (Voice TabNoteHead font-size -4)
%                           (Voice Dots font-size -3)
%                           (Voice Stem length-fraction 0.8)
%                           (Voice Stem no-stem-extend #t)
%                           (Voice Beam beam-thickness 0.5)
%                           (Voice Beam length-fraction 0.8)
%                           (Voice Accidental font-size -4)
%                           (Voice AccidentalCautionary font-size -4)
%                           (Voice Slur direction ,DOWN)
%                           (Voice Script font-size -3)

%                           (Voice StringNumber font-size -8)
%                         )
%          }
%  }

}
