double-repeat-barline at page break not good :-(

[Roland Goretzki]

Hi,

lilypond-version is 2.2.0.

If there are two areas of repeats in a piano-piece directly one after
another, lilypond creates automatically a correct double-repeat-barline
(":|:").

Unfortunately, in one piece this double-repeat-barline appears at page
break, and what happens, is the following:

The repeat-barline on the first page is correct like ":|" over the two
staffs of piano-music, but the second ("|:"), which appears on the
second page at first after the keys, is broken between the two staffs of
piano-music.

first page:     :||             second page:      ||:
                 ||
                :||                               ||:

I can't find a solution to correct it.

What did I not see? Or is it a bug?

Best Regards           Roland
