I have to correct myself: This is intentional. The space is part of
the header markup to emit the page number. On the first page, the
page number is suppressed by default, thus only the space remains.
To suppress headers and footers, add the following to the \paper
block of your .ly file:
oddHeaderMarkup = #f
evenHeaderMarkup = #f
oddFooterMarkup = #f
evenFooterMarkup = #f
Doing this, you get good bboxes.
