URL-s are broken after merging PDF files [duplicate]

How to preserve hyperlinks in included pdf?

After I merge PDF documents with pdflatex and pdfpages as described here, the URL-s are either broken (PDF files from OpenOffice), or their colorbox is missing (hyperref), or if they span over two lines only the information from the first line is kept (the original PDF was correct).

Can this be fixed? Or is it a known issue?
