BUG: lines repeated in PDF conversion

[Simons Mith]

This is likely to be a bitch to reproduce in a shorter file (130MB for current, sorry)

I had set up an epub-pdf conversion profile that tweaks the text, put line breaks in etc as I desire. Just noticed that at the end of one page I have a sentence fragment that is repeated overleaf. This is not present in the HTML, but in the PDF, the converter has presumably accumulated a big enough rounding error to repeat some text.

Is this a known issue? I'm hoping it is!

[Edit: I did note in an earlier post that a (Firefox) web page millimeter and a (Atril/Okular) pdf millimeter and an actual real-world millimeter do not agree particularly closely. I made a page with a set of coloured divs of widths 185, 186, 187, ... up to about 220mm and printed them out on an A4 sheet, and, allowing for printer margins the agreement with the width of a sheet of A4 - and with actual millimeters - was poor. I wouldn't be surprised if this was another manifestation of the same problem.]
