Attached, there are two files that are nearly similar, but behave different when
they are inserted into an empty document via "Insert->File...". Here is how to
reproduce:

1) create a new empty writer document
2) Insert->File... and select the attached file pagebreak_noSection.odt

The content of pagebreak_noSection.odt is shown at the FIRST page of the result
document. Thats correct!

The file pagebreak_noSection is very simple: there are only two paragraphs with
the content "a" and "b". The first paragraph is formatted with the set
formatting option Format->Paragraph/TextFlow/Breaks/Insert (Type Page).

When inserting that document into the new empty document, the insert method
correctly recognizes that there is no content at the first page of the empty
document (so the document already starts with a new page) and DOES NOT produce a
pagebreak.

NOW:

1) create a new empty writer document
2) Insert->File... and select the attached file pagebreak_WITHSection.odt

The content of pagebreak_WITHSection.odt is shown at the SECOND page of the
result document. Thats NOT correct! The correct behaviour would be to show the
content at the first page.

The file pagebreak_WITHSection differs from the first document only in one small
point: there is a section around the first paragraph "a".

When inserting that document into the new empty document, the insert method
wrongly creates a new paragraph before the section. Hence the document is no
longer empty and an unwanted pagebreak is produced. I think everything would be
OK, if the empty paragraph before the inserted section would not be produced in
this case.
