Lilypond crashes with SIGSEGV when creating an emtpy MIDI file

When running lilypond on LY-input broken.ly (s. below), lilypond crashes with SIGSEGV and a temporary  file named like broken.midi.0123abcd remains.

The desired output would be a correct MIDI file without any note on/off events.

\version "2.22.0"
\score {
   \new voice {
      \set Score.skipTypesetting = ##t
      c'
    }
  \midi {}
}

I hope someone can fix it.

This is waht I found, the creation of a Midi_walker fails because the audio_column_ of audio_items such as the track name does not get initialized.
