Hi,
A few PDFs, such as http://www.agc.army.mil/GeoPDFgallery/3D/Seattle.pdf ,
generate the following segfault when running podofopdfinfo :
==7589== Process terminating with default action of signal 11 (SIGSEGV)
==7589== Access not within mapped region at address 0x18
==7589== at 0x48BF66: PoDoFo::PdfVariant::DelayedLoad() const
(PdfVariant.h:530)
==7589== by 0x4BAE51: PoDoFo::PdfVariant::GetArray() (PdfVariant.h:758)
==7589== by 0x4E404D:

PoDoFo::PdfDictionary&) (PdfNamesTree.cpp:481)
==7589== by 0x4E3E0D: PoDoFo::PdfNamesTree::ToDictionary(PoDoFo::PdfName
const&, PoDoFo::PdfDictionary&) (PdfNamesTree.cpp:456)

==7589== by 0x48A14E: main (podofopdfinfo.cpp:147)
The following patch fixes that segfault :
