This was caused by my patch for Issue 4281, an oversight.

For now I suggest to use:

\layout {
  \context {
    \type "Performer_group"
    \consists "Staff_performer"
    \name ChordNames
    \defaultchild Voice
  }
}

Could you confirm that it works for you?

Then I'll put up an issue on the tracker. Patch will follow soon.


Sorry for the inconvenience,
