Incorrect bar line with voltas, \repeatTie and lyrics

[Ole V. Villumsen]

If I leave out the lyrics from the example below, Lilypond sets the notes 
nicely reporting no errors or warnings. When I include the lyrics, Lilypond 
counts the measure in the second volta wrong. One, it now reports:

7-8.ly:11:40: warning: barcheck failed at: 7/8
            \volta 2 { g2\repeatTie e2
                                        | }

Two, it now incorrectly sets a bar line between the two notes in the second 
volta, close to the first note, and no bar line at the end of the piece. I 
suspect that the bar line is set 1/8 into the second volta. This seems to agree 
with its position and with the warning message.

I expect that one can work around it (which I haven’t attempted yet).

    \new Voice = "one" {
      \relative {
        \repeat volta 2 {
          g'1 ~ |
          \alternative {
            \volta 1 { g2 r4. g8 | }
            \volta 2 { g2\repeatTie e2 | }
          }
        }
      }
    }
    \addlyrics {
      \repeat volta 2 {
        Ah,
        \alternative {
          \volta 1 { ah, }
          \volta 2 { _ oh. }
        }
      }
    }
