Crash when signing a document with PADES

[Leuca]

Caused by using the version of PoDoFo shipped by Fedora/RHEL. A patch allows the code to link against a shared version of the library but it is not enough to support PADES.

The culprit seems to be PoDoFo::PdfPagesTree::GetTotalNumberOfPages()

# A fatal error has been detected by the Java Runtime Environment:

After some changes that should improve the broken part of library there is a new problematic frame:

#

Note: This crash happens when signing with graphical signature

Also this warning could be interesting. Happens both with and without graphical signature.
