File source-poppler-0.59.1.dif of Package texlive
Dear Werner, > See attachment for figure_fsteps.pdf ... Please test attached pdftoepdf.cc and pdftosrc.cc on SUSE. They are working fine on windows for your example with the poppler 0.60.1. Simply replace pdftoepdf.cc and pdftosrc.cc in web2c/pdftexdir by the attached files.
