The OS X PDF doesn't use the font that the ODT specifies (PDF: Helvetica vs. ODT: FreeSans), so one might think that differing fonts are responsible for the spacing differences. Would be nice to have an OS X PDF with the correct font to see if there are differences between the platforms at all.
But even without a usable file for comparison, the spacing on dapper looks wrong. -- Openoffice.org writer incorrectly displays single line spacing as 1.5 line spacing in Dapper PPC https://launchpad.net/bugs/58123 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
