Confirmed.  Looks like a strange artifact of the \fill-line markup 
(containing both poet and composer) w.r.t. a negative first X-extent 
entry of a \center-column, IIUC.
A workaround/solution is to use \left-align before the \center-column. 
No \right-align is not necessary for the right part (composer), by the way.

  poet = \markup \left-align \center-column { ... }
