Ah, now i understand better what you mean.
I'm sorry, but you're mistaken.  A partial measure doesn't have to be
balanced anywhere; a composer may choose to do whatever he wishes in
this regard.  For example, this is perfectly valid:

{
  \clef F
  \key f \major
  \partial 8 a8
  bes8 c' a bes g4. f8
  f4 c f, r
}

Well, i don't get any error message.  What error message did you get?

Well, LilyPond as a rule doesn't insert the final barline anywhere -
she inserts just the barlines that result from the meter.

to print a final barline, use \bar "|."

I think i may have an idea what is causing your confusion.  From the
above code it seems that you expect \partial to work on the whole
music expression that follows it.  In other words, i suppose you are
expecting that

\partial 4
{
  a4
  \repeat volta 2 {
    a b c d
    a b c d
  }
}

will mean that music expression

{
  a4
  \repeat volta 2 {
    a b c d
    a b c d
  }
}

should be time-shifted by a quarter note.  That's not how partial measures work.
I hope that this explanation will help you...

best,
Janek
