Hi Kent,
I do not have any PDF-tooling (apart from viewers), and my knowledge of the format is also very limited. The magazine is
here, bottom of the page, click on 'free sample' and then Save as PDF (page 26 has the problem), in case anyone wants to take a look at it (Not sure if this works on linux). (@Kent its about software testing so probably not that interesting for you
). There are new versions of the poppler library, I assume this issue is already fixed. If I find the time I can have a look at newer versions of the library.
