Comment 4 for bug 409673

from an ltrace of pdflatex w/ bad poppler lib

_Znwj(284, 0x1a787d, 0, 0x28bff4, 0x28bff4) = 0x9298cd0
_ZN12GlobalParamsC1EPKc(0x9298cd0, 0, 0, 0x28bff4, 0x28bff4) = 0x28d3a0

and with good poppler lib

_Znwj(284, 0x4a887d, 0, 0x58cff4, 0x58cff4) = 0x993bc88
_ZN12GlobalParamsC1EPKc(0x993bc88, 0, 0, 0x58cff4, 0x58cff4) = 0x58e3a0
_ZN12GlobalParams11setErrQuietEi(0x993bc88, 0, 0, 0x58cff4, 0x58cff4) = 0
_Znwj(24, 0, 0, 0x58cff4, 0x58cff4) = 0x9948c80
xstrdup(0x9938e38, 0, 0, 0x58cff4, 0x58cff4) = 0x9948bf0
_Znwj(32, 0, 0, 0x58cff4, 0x58cff4) = 0x9948bc8
_ZN9GooStringC1EPKc(0x9948bc8, 0x9948bf0, 0, 0x58cff4, 0x58cff4) = 0x9948bc8
_Znwj(48, 0x9948bf0, 0, 0x58cff4, 0x58cff4) = 0x9948ca0
_ZN6PDFDocC1EP9GooStringS1_S1_Pv(0x9948ca0, 0x9948bc8, 0, 0, 0) = 1
_ZN4XRef9okToPrintEi(0x9948f80, 0, 0, 0, 0) = 1

nothing obviously different to me (i.e. function failing or something).
