This effect seems to be a consequence of
ragged-right = ##f together with a second bar
containing a single note (or space).  When
the second bar is stretched to fill the line
the note gets displaced almost to the centre
of the bar.  This simpler example shows the
same effect:

\paper {
 ragged-right = ##f
}
{
 a'1
 a'1^"foobar"
}

The spacing may not be optimum, but I'm
not sure I'd call it a bug.  After all,
stretching this out to a full line is never
going to look right, whatever you do.
